Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary transportation in coal mines, and particularly relates to a carrier frame of a support carrier vehicle. Background Art

[0002] As a safe and efficient auxiliary transportation device, the trackless rubber-tyred vehicle is an important guarantee for the safe production of the mine. When installing and withdrawing the large equipment at the coal mining face, the transportation of large equipment mainly relies on the trackless rubber-tyred vehicle. Before the transportation operation, the corresponding type of trackless rubber-tyred vehicle is selected according to the type, size and weight of the equipment. Among them, the hydraulic support is transported by the support carrier vehicle, and the electric train equipment is transported by forklifts with different tonnages such as 55T forklifts and 25T forklifts.

[0003] When using 55T forklifts and 25T forklifts to shovel and transport the electric train equipment, due to the large volume of the electric train, during the transportation process of the forklift, most of the driver's vision is blocked by the electric train equipment. Especially when turning, the signalman needs to get off the vehicle to direct in order to pass safely. In this transportation mode, the driver must drive at a low speed, with a slow running speed, and at the same time, it is extremely easy to have collision and rubbing accidents, resulting in low transportation efficiency. At the same time, the total length of the forklift itself plus the length of the electric train reaches more than 16 meters. When passing through special transportation sections such as turning and roadway entrances, a large turning radius is required, but it is limited by the space conditions at the underground site, and it is easy to have rubbing and collision accidents, with a high safety control risk. Content of the Utility Model

[0004] Aiming at the problems such as poor driver's vision, slow driving speed, large turning radius and extremely easy occurrence of collision and rubbing accidents when using forklifts to shovel and transport large equipment such as electric trains, the utility model provides a carrier frame of a support carrier vehicle.

[0005] The utility model adopts the following technical scheme:

[0006] A carrier frame of a support carrier vehicle, including a carrier frame body located at the bottom of the electric train equipment to be transported, the carrier frame body includes carrier rods, and suspension devices for connecting with the lifting chain hooks of the hoisting machines of the support carrier vehicle are arranged at both ends of the carrier rods.

[0007] Further, the length of the carrier rod is the same as the width of the U-shaped frame of the rear frame of the support carrier vehicle.

[0008] Further, the number of the carrier frame bodies is two, which are respectively located at the front and rear ends of the bottom of the rear frame of the support carrier vehicle.

[0009] Further, the suspension device includes a connecting block, and suspension holes are arranged on the surface of the connecting block.

[0010] Furthermore, the suspension devices at both ends of the load-bearing rod are symmetrically arranged with respect to the center of the load-bearing rod.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By using the present utility model to transport equipment such as electric trains, compared with the previous use of 55T, 28T, and 25T forklifts for shoveling and transporting, the driver of the support carrier vehicle has a wider field of vision during transportation, and the probability of bumping and scratching is greatly reduced. The driver can drive the support carrier vehicle at a normal speed, greatly improving the transportation safety efficiency. At the same time, during transportation, the turning radius required when turning is small, reducing the occurrence probability of bumping and scratching accidents when passing through special transportation sections such as turns and alley entrances.

[0017] In combination with the drawings, the present utility model will be further described.

[0018] As shown in the figure, a support carrier vehicle load-bearing frame includes a load-bearing frame body located at the bottom of the electric train equipment to be transported. The load-bearing frame body includes a load-bearing rod 1, and suspension devices for connecting with the lifting chain hooks of the hoist of the support carrier vehicle 4 are provided at both ends of the load-bearing rod 1.

[0019] Among them, the load-bearing rod 1 is two I-beams (model 12#) with a length of 1.9 meters, and the length is the same as the width of the "U" - shaped frame of the rear frame of the support carrier vehicle.

[0020] The suspension device includes a connecting block 2, and a suspension hole 3 is provided on the surface of the connecting block 2.

[0021] The suspension device is cut from 4 steel plates with a length of 300mm, a width of 100mm, and a thickness of 60mm. A rectangular suspension hole with a length of 100mm and a width of 50mm is cut at one end of the long side of the steel plate, and the other ends are respectively welded to both ends of the load-bearing frame.

[0022] The usage method of the present utility model is as follows:

[0023] When it is used at locations with lifting equipment such as transfer stations, first hang the carrier frame of the present utility model on the support carrier vehicle. When hanging, respectively hook the lifting chain hooks of the four lifting mechanisms of the support carrier vehicle onto the four suspension holes of the carrier frame, so that the carrier frame is kept at a height of about 150 mm from the bottom plate. Then use the lifting equipment to lift the electric train to a height of more than 300 mm from the bottom plate. The driver drives the support carrier vehicle to reverse along the longitudinal direction of the electric train until the electric train is contained within the "U"-shaped frame of the support carrier vehicle. Operate the lifting control handle of the support carrier vehicle, the lifting oil cylinder extends, drives the lifting connecting rod to rotate, the lifting chain and the carrier frame rise, lift the electric train, remove the hook of the lifting equipment, and use the anchor chain to connect and tighten the electric train body to the fixing ring on the "U"-shaped frame of the support carrier vehicle to prevent the electric train from slipping out and separating from the carrier frame when going downhill during transportation. Then the driver can drive the support carrier vehicle to perform normal transportation operations.

[0024] When it is used at other locations, first use the plate girder to raise the electric train to a height of more than 300 mm from the bottom plate. Place one special carrier frame of the support carrier vehicle through the longitudinal two ends under the electric train respectively. The driver drives the support carrier vehicle to reverse along the longitudinal direction of the electric train until the electric train is contained within the "U"-shaped frame of the support carrier vehicle. Use the lifting chain hooks of the four lifting mechanisms of the support carrier vehicle to hook the four suspension holes of the special carrier frame of the support carrier vehicle. Operate the lifting control handle, the lifting oil cylinder extends, drives the lifting connecting rod to rotate, the lifting chain and the carrier frame rise, lift the electric train, use the anchor chain to connect and tighten the electric train body to the fixing ring on the "U"-shaped frame of the support carrier vehicle to prevent the electric train from slipping out and separating from the carrier frame when going downhill during transportation. Then the driver can drive the support carrier vehicle to perform normal transportation operations.

[0025] The present utility model has the following beneficial effects compared with the prior art:

[0026] Economic benefits: When using forklifts such as 55T and 25T for shoveling and transporting, due to the blocked sight, the average driving speed of the driver is about 5 km / h. After using the support carrier vehicle for transportation, the driving speed of the driver can reach 15 km / h, greatly improving the transportation efficiency and reducing the collision and scratching accidents. Taking the electrical train transportation in the 1309 working face of Chengzhuang Coal Mine as an example: The total length of the transportation line is about 6 km. It takes 6 km÷5 km / h = 1.2 hours to transport one trip using a forklift. After using the support carrier vehicle, the transportation time is 6 km÷15 km / h = 0.4 hours, and the transportation time is shortened by 0.8 hours (48 minutes). Calculated according to 20 equipment need to be transported for each working face installation and recovery, and there are 5 installations and recoveries in the working face in 2023, the annual labor time can be saved by 0.8×20×5 = 80 hours. At the same time, the collision and scratching accidents are greatly reduced, saving a large amount of equipment maintenance costs.

[0027] Social benefits: When using the special carrier for the support vehicle to transport equipment such as electric trains, compared with using 55T, 28T, and 25T forklifts for shoveling and transporting in the past, the driver of the support vehicle has a wider field of vision during transportation, and the probability of bumps and scratches is greatly reduced. The driver can drive the support vehicle at a normal speed, which greatly improves the transportation safety efficiency. At the same time, the turning radius required during turning in the transportation process is small, reducing the occurrence probability of bumps and scratches accidents when passing through special transportation sections such as turns and alley entrances.
