低成本、率、以工作质量保证产品质量

叉车门架是叉车工作装置提升货物的机构，又称为门架。由内门架、外门架、货叉架、货叉、链轮、链条、起升油缸和倾斜油缸等组成。叉车门架设计应该如何进行？下面济南二手叉车厂家为你分析：

Forklift gantry is the mechanism for lifting goods by forklift working device, also known as gantry. It is composed of inner mast, outer mast, fork frame, fork, sprocket, chain, lifting cylinder and tilt cylinder. How to design the forklift mast? Jinan second-hand forklift manufacturer will analyze for you:

货叉是叉车的基本和通用的取物装置。一般叉车都装有两个同样的货叉。

Fork is the basic and universal pickup device of forklift. Generally, forklifts are equipped with two identical forks.

货叉装载叉架上。它的外形是一个L形杆件，分为水平段和垂直段两部分。一般货叉的水平段和垂直段做成整体的，称为整体式货叉。有的小吨位叉车的水平段和垂直段分别制成，用销轴连接起来水平段既可以平置，又可以向上折起，与垂直段靠拢称为折叠式货叉。本次设计采用整体式货叉。

The fork is loaded on the fork rack. Its shape is an L-shaped member, which is divided into horizontal section and vertical section. Generally, the horizontal section and vertical section of the fork are made into a whole, which is called the integral fork. The horizontal section and vertical section of some small-tonnage forklifts are made separately, and the horizontal section can be flat and folded up by connecting with the pin shaft. The horizontal section close to the vertical section is called folding fork. This design adopts integral fork.

在叉车叉取货物时，货叉的水平段用来插入货物或托盘的底部，叉起后，用来承载货物。因此，火车水平段的上表面必须水品，水平前端的下表面略有倾斜，以使叉尖出厚度较薄，并且前端逐渐变窄，叉尖两侧带有圆弧，这样有利于是货叉插入货物底部，叉取货物。

When the forklift picks up the goods, the horizontal section of the fork is used to insert the goods or the bottom of the pallet, and after the fork is lifted, it is used to carry the goods. Therefore, the upper surface of the horizontal section of the train must be watered, and the lower surface of the horizontal front end is slightly inclined, so that the fork tip is thinner, and the front end gradually narrows, with arcs on both sides of the fork tip, which is conducive to inserting the fork into the bottom of the goods and forking the goods.

货叉的垂直段用来与叉架连接，根据连接的形式不同，分为挂钩型和交接型两种。为了在叉架上定位货叉，在上部挂钩上设置有定位销。定位销插入叉架上横梁的凹槽中，以防止货叉任意移动。调解室，往上提起定位销，克服弹簧力，销轴脱离叉架上横梁凹槽，便可移动货叉，改变间距。

The vertical section of the cargo fork is used to connect with the fork frame. According to the connection form, it can be divided into two types: hook type and joint type. In order to position the fork on the fork frame, a locating pin is arranged on the upper hook. The locating pin is inserted into the groove of the cross beam on the fork frame to prevent the fork from moving arbitrarily. In the mediation room, lift up the locating pin, overcome the spring force, and the pin shaft will disengage from the groove of the upper crossbeam of the fork frame, so as to move the fork and change the spacing.

根据叉架在门架系统中的相关位置，货物的重量考叉架传给起重链条，货物重量产生的力矩通过叉架传给门架，链条带动叉架升降时，叉架要可靠地沿着门架导轨运动。

According to the relevant position of the fork frame in the gantry system, the weight of the goods is transferred to the lifting chain through the fork frame, and the moment generated by the weight of the goods is transferred to the gantry through the fork frame. When the chain drives the fork frame to rise and fall, the fork frame must move reliably along the gantry guide rail.

货叉或其他属具可以从叉架侧面装上或卸下，当叉架上装有挡货架时，侧面不便装拆，叉架下横梁中间开一缺口，可以方便装拆货叉。为了是货叉或其他属具在叉架上定位，在框架上横梁上对称地做有若干定位孔或定位槽，在货叉上端的挂钩上装有带弹簧的定位销。根据货物的尺寸，货叉可以再叉架上滑动以调整两叉的间距，并定位在合适的位置上。

Forks or other accessories can be loaded or unloaded from the side of the fork frame. When there is a shelf on the fork frame, it is not easy to install and disassemble the side. There is a gap in the middle of the lower beam of the fork frame to facilitate the loading and unloading of forks. In order to position the fork or other accessories on the fork frame, several locating holes or slots are symmetrically made on the upper crossbeam of the frame, and the hook at the upper end of the fork is equipped with locating pins with springs. According to the size of the goods, the fork can slide on the fork frame to adjust the spacing between the two forks and locate them in the proper position.

叉架上的滚轮式把货物的重力，以力偶矩的形式传递给门架。因为滚轮是固定间距，对门架立柱的作用力大，应合理布置。侧向轮承受叉架的侧向力，由于货物在货叉上的放置的不对中，或在有倾斜的路面运行等都会产生侧向力，为防止叉架对门架正常的运动被卡住，装设侧向滚轮是必须的，而且为增大侧向滚轮间距可使用中和滚轮。

The roller type on the fork frame transfers the gravity of the goods to the portal frame in the form of couple moment. Because the rollers are fixed spacing, the force on the mast column is large and should be reasonably arranged. The lateral wheel bears the lateral force of the fork frame. Because the goods are placed incorrectly on the fork, or run on a sloping road, it will produce lateral force. In order to prevent the normal movement of the fork frame to the portal frame from being blocked, it is necessary to install the lateral roller, and to increase the distance between the lateral rollers, the neutralizing roller can be used.
