Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery and mining engineering, and in particular relates to a liftable small trackless equipment driver's shed. Background Art

[0002] The driver's shed is an important part of small trackless equipment. It can effectively protect the operators of small trackless equipment from being hit by falling rocks in the well and protect the safety of operators. The driver's shed of small trackless equipment is generally made of lightweight materials and fixedly installed on the frame.

[0003] At present, small trackless equipment is restricted by underground mine tunnels. In order to ensure the size and turning radius of the vehicle itself, an open driver's shed is generally used. It is welded and riveted to the frame of the small trackless equipment. The disassembly, installation and maintenance of the driver's shed are relatively cumbersome. Affected by the vehicle's own external dimensions, the height of the driver's shed is generally not adjustable, which is not conducive to the operator's operating field of view and driving experience. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a liftable small trackless equipment driver's shed.

[0005] The technical solution provided by the utility model is as follows: a liftable small trackless equipment driver's shed, comprising a left side plate of a front frame and a right side plate of a front frame, characterized in that a left support and a right support are respectively connected to the left side plate of the front frame and the right side plate of the front frame; a support column is respectively connected to the left support and the right support, each support column is plugged with a column, and the support column and the column are adjustably connected through corresponding connecting holes, fixed pin shafts, and cotter pins; the left and right columns are connected to the ceiling through the support plate, each support column is provided with a hydraulic jack connected to the column, each hydraulic jack is connected to a first oil pipe, each first oil pipe is provided with a stop valve, each first oil pipe is connected to a diverter, and the diverter is connected to a manual pump through a second oil pipe.

[0006] Furthermore, a lifting ring is connected to the center of gravity of the ceiling.

[0007] Furthermore, a lamp holder is provided on the support column, and an LED lamp is connected to the lamp holder.

[0008] The beneficial effects of the utility model are as follows: the utility model connects the left and right support columns and the left and right uprights between the front frame and the ceiling, and installs a separate hydraulic jack, and controls the stroke of the jack through the stop valve on the hydraulic jack, thereby controlling the lifting and lowering of the ceiling by driving the lifting and lowering of the left and right uprights. In order to prevent the ceiling from falling due to sudden damage to the stop valve of the hydraulic jack, the left and right support columns and the left and right uprights are connected adjustable through corresponding connection holes, left and right fixed pins, and left and right cotter pins, thereby increasing mechanical locking, ensuring the height of the ceiling, and ensuring the safety of the equipment operator. The utility model solves the shortcoming that the driver's shed of small trackless equipment cannot be adjusted, and can be adjusted according to the actual situation of the mine tunnel. It has a simple structure, is easy to disassemble and install the driver's shed, can meet the assembly process requirements of the equipment, has strong reliability, and has a low failure rate. There is no need to reprocess the vehicle body, so the maintenance is time-consuming and low-cost, and does not affect the previous stress state of the vehicle frame.

DETAILED DESCRIPTION

[0012] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0013] like Figure 1 , Figure 2As shown, a liftable small trackless equipment driver's shed includes a front frame left side plate 9 and a front frame right side plate 12, and a left support 8 and a right support 10 are welded on the front frame left side plate 9 and the front frame right side plate 12 respectively. A support column 3 is connected to the left support 8 and the right support 10 respectively, and each support column 3 is provided with a lamp holder 4, and an LED lamp 13 is fixed to the lamp holder 4 through a nut 14. A column 2 is inserted into each support column 3, and corresponding connecting holes are provided on the support column 3 and the column 2, and a fixed pin shaft 5 is inserted into the connecting hole, and the fixed pin shaft 5 is connected to the cotter pin 6, so as to realize the adjustable connection between the support column 3 and the column 2. The left and right columns 2 are connected to the ceiling 1 through the support plate, and a lifting ring 11 is connected to the center of gravity of the ceiling 1 for easy lifting. A hydraulic jack 7 is provided in each support column 3, and the hydraulic jack 7 is connected to the column 2. Each hydraulic jack 7 is connected to a first oil pipe 18, and each first oil pipe 18 is provided with a stop valve 19. Each first oil pipe 18 is connected to a diverter 17, and the diverter 17 is connected to a manual pump 15 through a second oil pipe 16.

[0014] When in use, hydraulic oil is pumped into the second oil pipe 16 through the manual pump 15, and the hydraulic oil passes through the diverter 17 and the two first oil pipes 18 to enter the left and right hydraulic jacks 7 respectively, to achieve the lifting of the hydraulic jacks 7. The hydraulic jacks 7 lift the column 2 to drive the ceiling 1 to move upward. After reaching a certain height, the stop valve 19 on the hydraulic jack 7 is used to fix the rising stroke of the ceiling 1, and the column 2 and the support column 3 are fixed by the fixing pin shaft 5 and the cotter pin 6, thereby realizing the mechanical fixation of the driver's shed to ensure safe use.
