A support truck and its frame

Abstract

The invention discloses a support transport vehicle and its frame. The frame comprises: an end support part, the end support part is integrated with accessory parts; The support arms are respectively arranged at both ends of the end support part; the support arms include the longitudinal beam body, the lower box structure and the upper box structure in sequence from bottom to top in the height direction of the vehicle frame. A first installation seat for installing a steering oil cylinder and a second installation seat for installing a hydraulic independent suspension are installed, and a steering mechanism is installed in the upper box structure. The frame integrates a number of accessory parts into the end support part, thereby improving the integration performance of the frame and making the structure of the frame more compact; at the same time, supporting arms are set on both sides of the end support part to ensure that the vehicle The structural strength of the frame is improved, and the support arm is a double-layer box structure, and the mounting seat and steering mechanism can be embedded in the support arm, thereby further improving the compactness of the frame.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a support transport vehicle and a vehicle frame. Background technique [0002] With the continuous development of underground large mining height working faces in recent years, fully mechanized mining equipment tends to be more and more powerful, large mining height, and intelligent. As a hydraulic power device for roof support and management, the hydraulic support has an increasing tonnage based on the need for large mining heights. The support truck is a new type of special tool specially developed for the reverse or long-distance transportation of the hydraulic support in the process of moving and reversing the fully mechanized mining face. It is an indispensable auxiliary transportation equipment for modern coal mining technology. [0003] However, in the traditional support truck, since the vehicle frame, as the main body part of the vehicle, needs to h...

Problems solved by technology

[0003] However, the traditional support truck needs sufficient strength and rigidity because the frame is used as the main part of the vehicle, resulting in a large volume and poor structural compactness.
