Description

High strength cross-country fork truck frame

Technical Field

The utility model relates to the technical field of forklifts, in particular to a high-strength off-road forklift frame.

Background

The traditional articulated fork truck is that parts such as portal frame are generally only installed on the front frame, and the driver's cabin sets up on the back frame, when using fork truck, because the driver's cabin position is relatively back, the front frame of installing the portal frame causes very big interference to driver's sight for the driver can not see the loading and unloading condition of goods in time, turns to for before turning to when fork truck turns round, and portal frame and front frame keep off the sight easily, lead the driver and can not see the road surface situation in time. The chassis of the traditional forklift is low, the steering axle is not driven, and is not of a swinging structure, and the steering wheel is prevented from being poor in tire gripping force and easy to misdrive, so that the forklift can only be used in places with good road conditions.

The off-road forklift is particularly suitable for loading and unloading cargoes on complex road surfaces and mountains. The off-road forklift needs to operate under the severe working condition, occasionally can touch falling rocks or other things which are harmful to a driver, and can appear the situation that the off-road forklift turns on one's side under extreme conditions. The installation of high strength protection on off-road forklifts has become extremely important. The protection of general engineering machine installation is that on the roof basis of driver's cabin increase intensity stand, then increase the protective cap on the stand, can only protect injury to the driver such as falling stone like this. But for large-tonnage large-scale equipment of FDM8200T cross-country fork truck, the whole machine quality is close to 27 tons, and the driver can not be well protected according to the protection structure of the existing cab when the equipment is turned on one's side.

Disclosure of Invention

Therefore, aiming at the problems, the utility model provides the high-strength cross-country forklift frame which has reasonable structure and can effectively play a role in safety protection when driving safety and rollover are improved.

In order to solve the technical problem, the utility model adopts the following scheme: the utility model provides a high strength cross country forklift truck frame, includes back frame body, still includes the protection frame, the protection frame includes two discrete pillars and locates the visor on pillar top, the visor has many rectangular tube welding to become the net frame and constitutes, and two pillar tops insert visor rear side both ends and pillar top and visor fixed connection, and two pillar lower extreme lateral part welding has the fixed plate, and two pillar lower extreme are fixed connection and the driver's cabin top that the visor is located back frame body mutually with back frame body through the fixed plate covers the driver's cabin.

Further improvement, the protection cap is divided into a plurality of field word check, and the buckle closure has the power piece that unloads on each field word check, it includes arc and spring to unload the power piece, and arc both ends are equipped with the draw-in groove towards the protection cap, and the arc passes through the draw-in groove lock on horizontal pole or the vertical pole in the field word check, the spring is located between the intersection of arc middle part and field word check interior horizontal pole and vertical pole.

Still further improvement, be equipped with the interval degree of depth between draw-in groove of arc and the horizontal pole or the longitudinal rod in the protection cap field check.

Further improvement, the protective cap is provided with a force unloading block, and the field grids are arranged in a spacing matrix.

By adopting the technical scheme, the utility model has the beneficial effects that: through set up the hood that covers the driver's cabin in the driver's cabin top of back frame body and on the fixed back frame body of back through two powerful pillars of hood through the fixed plate, touch falling rocks or other things that constitute the injury to the driver smash when falling, accessible hood effectively blocks, even appear cross-country fork truck under extreme circumstances and roll over the time because the existence of pillar and hood makes the driver's cabin can not earlier with hard thing collision threat driver's safety in the driver's cabin, form the effectual protection of one deck, rational in infrastructure, improve driving safety. Through further setting, the setting of unloading the power piece makes falling stones etc. smash falling and the protective cap can not appear directly hard to bump hard, but forms a buffering and unload the power, strengthens the protection intensity of protective cap, further strengthens the safety protection performance of use, can extensively popularize and apply.
