Embodiment Construction

[0033] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the dual-purpose underground support truck for dragging and shoveling of the invention includes a front part 1, a connecting part 2 and a trailer frame 3 or a shovel 4 connected to the connecting part 2. The front part 1 includes a front frame 6, and the front part of the front frame 6 Radiator 7, driver's cab 5, explosion-proof engine 11 for power system, front wheel 9 in the middle, steering system at the rear, steering system includes steering hydraulic oil tank 12, steering oil cylinder 14, oil pump, etc., power system, steering The structure of the system is the same as that of the existing forklift. The driver's cab 5 is a lateral driver's cab, that is, the driver's direct vision direction is perpendicular to the driving direction of the vehicle, so that the driver can observe the front and rear road conditions at any time.

[0034] The connecting part 2 comprises a rear frame 8, the front end of th...

Abstract

The invention discloses a drag shovel multipurpose car and a method for enabling an underground support to enter a cage. The drag shovel multipurpose car can convey a whole hydraulic support to the cage once without need of disassembling the hydraulic support, and during the process from entry of the whole hydraulic support into the cage until retreat of the drag shovel multipurpose car, the drag shovel multipurpose car guarantees that the cage is not overweight and simultaneously guarantees that the gravity center of the hydraulic support is located in a needed position in the cage, and thereby guarantees that the gravity center of the cage does not shift. The drag shovel multipurpose car and the method for enabling the underground support to enter the cage solve use risk caused due to the fact that the support is disassembled so as to descend a well, avoids time loss caused by disassembly and assembly of the support, improves descending speed of the support, improves production efficiency, reduces coal mine production cost, and easily controls the support during the conveying process of the support. The drag shovel multipurpose car can achieve fast switching between a drag car and a shovel car, wherein the drag car is used to complete transport work of hauling the support for a long distance and enabling the support to enter the cage, and can be rapidly switched to the shovel car after the transport work of the underground support is finished, and the shovel car is used to transport goods for a short distance. Furthermore, the drag shovel multipurpose car for enabling the underground support to enter the cage obtains multiple functions, and accordingly the production cost is reduced, and resource waste is avoided.

Description

technical field [0001] The invention relates to a transport vehicle, in particular to a multi-purpose vehicle for dragging and shoveling an underground bracket into a cage and a method for putting the bracket into the cage. Background technique [0002] At present, the underground support truck includes a head part and a trailer frame, and the head part is provided with a cab, a power system, and the like. It is only used for the transportation of underground supports, and after the support transport vehicle has transported the support to the destination, the support transport vehicle cannot be used for other purposes. [0003] Later, a dual-purpose underground support truck with drag and shovel (patent application number 201110045882.X) appeared. But the car can only carry the support into the cage on the basis that the weight of the support is far less than the carrying capacity of the cage. [0004] In order to ensure the smooth entry of the support into the cage, the s...
