Description

Technical Field

[0001] The utility model belongs to the technical field of transporting hydraulic columns, and in particular relates to a special vehicle for transporting hydraulic columns. Background Art

[0002] A hydraulic column is a device that uses the hydraulic principle to achieve force transmission and motion control. A hydraulic column, also known as a hydraulic support, is a device that supports or pushes objects through liquid pressure; the working medium (hydraulic oil) is drawn into the pump body through the suction of the hydraulic pump; inside the pump body, the hydraulic oil is compressed to form a certain pressure; the hydraulic pump sends the compressed hydraulic oil to the top (or bottom) of the hydraulic cylinder through a pipeline; after the hydraulic oil enters the hydraulic cylinder, it drives the piston to move in the corresponding direction, thereby generating a certain thrust or pull; the control valve inside the hydraulic cylinder adjusts the flow direction of the hydraulic oil according to the input of the control signal to control the movement of the piston; when the control signal is revoked or changed, the activity of the hydraulic column stops and the piston will remain in its current position.

[0003] There are many types of hydraulic columns, including single hydraulic columns (such as suspended type, double telescopic suspended type, DN internal injection type and fiberglass single hydraulic columns) and hydraulic columns used for other mechanical equipment; hydraulic columns are mainly composed of hydraulic cylinders, hydraulic pumps, control valves and working media (hydraulic oil), etc., and single hydraulic columns are composed of cylinder bodies, pistons, valves and other parts.

[0004] In Ⅲ23033 lane, goaf-side tunnel construction is carried out. The construction requires that the flexible formwork wall be cast along with the progress of the mining face. There are hydraulic column π-type beam sheds in the lane for advance support. The π-type beam sheds are erected in three rows along the lane, with a spacing of 1 meter between hydraulic columns; the spacing between hydraulic columns of the flexible formwork wall is 0.5-0.7 meters. When the flexible formwork wall is cast to a length of more than 200 meters, the hydraulic columns within 200 meters of the flexible formwork wall are retrieved and transported outside the coal mining working face for recycling. About 7 hydraulic columns are retrieved for each 3-meter-long flexible formwork wall. Since the construction site is relatively narrow and the existing transport vehicles are large in size, it is not convenient to drive in the narrow space and need to be manually lifted and transported, which makes the construction time-consuming and labor-intensive, and inconvenient for the staff to transport and use the hydraulic columns. Therefore, a special vehicle for transporting hydraulic columns is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a special vehicle for transporting hydraulic columns, so as to solve the problem that the construction site space is relatively narrow, and the existing transport vehicles are large in size and inconvenient to drive in the narrow space, and need to be lifted manually, which makes the construction time-consuming and labor-intensive, and inconvenient for the workers to transport and use the hydraulic columns.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] Through the setting of the above-mentioned technical scheme, the cooperation between the rotating shaft, the moving wheels, the support plate and the push handle frame is utilized to form a vehicle that can travel in a narrow space, thereby reducing the size of the transport vehicle. Correspondingly, it is convenient for this transport vehicle to travel in a narrow space, and there is no need for manual lifting, which makes the construction time-consuming and labor-intensive, and facilitates the staff to transport and use the hydraulic column.

[0009] The clamping mounting mechanism includes a square slide groove opened on the top of the support plate, a servo motor is fixedly connected to one side of the inner wall of the square slide groove, a threaded rod is fixedly connected to the output end of the servo motor, and the threaded rod rotates away from one end of the servo motor and extends to the other side of the square slide groove, a limiting plate is fixedly connected to the inner middle position of the square slide groove, and a threaded block is threadedly connected to the outer wall of the threaded rod between the square slide groove and the limiting plate, a clamping plate is fixedly installed on the top of the threaded block, and a sliding baffle is connected to one side of the clamping plate.

[0010] Through the arrangement of the above technical solution, when the workers transport the hydraulic column, the clamping plate is used to clamp the hydraulic column, thereby improving the stability of the hydraulic column during transportation and improving the work efficiency of the workers in transporting the hydraulic column.

[0011] When this transport vehicle is not in use, the servo motor can be turned on to shorten the distance between the two clamping plates to the shortest. At this time, the sliding baffle and the top of the square slide can slide and fit together to protect the servo motor and threaded rod inside the square slide, avoiding corrosion damage to the servo motor and threaded rod, thereby improving the work efficiency of the staff in using this transport vehicle to transport the hydraulic column.

[0012] Preferably, a rotation groove is provided on the moving wheel, the rotation groove is correspondingly arranged to the rotation shaft, and the moving wheel is rotationally connected to the rotation shaft through the rotation groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By utilizing the cooperation between the rotating shaft, the moving wheel, the supporting plate and the push handle frame, a vehicle that can travel in a narrow space is formed, which reduces the volume of the transport vehicle and accordingly facilitates the transport vehicle to travel in a narrow space. There is no need for manual lifting, which makes construction time-consuming and labor-intensive, and facilitates the transportation and use of the hydraulic column by the staff;

[0019] When the workers transport the hydraulic column, the clamping plate is used to clamp the hydraulic column, which improves the stability of the hydraulic column during transportation and improves the work efficiency of the workers in transporting the hydraulic column.

At this time, the sliding baffle and the top of the square slide can slide and fit together to protect the servo motor and threaded rod inside the square slide, avoiding corrosion damage to the servo motor and threaded rod, thereby improving the work efficiency of the staff in using this transport vehicle to transport the hydraulic column.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 、 Figure 2 、 Figure 3 As shown, a special vehicle for transporting hydraulic columns comprises a rotating shaft 1, with moving wheels 2 rotatably connected at both ends of the rotating shaft 1, and two support plates 3 fixedly connected to the outer wall of the rotating shaft 1 between the two moving wheels 2, a push handle 4 fixedly connected between the two support plates 3, and a clamping and mounting mechanism connected to the support plates 3 for clamping and fixing the transported hydraulic columns;

[0028] The present invention is further specifically described in detail. A rotation groove is provided on the moving wheel 2. The rotation groove is corresponding to the rotation shaft 1. The moving wheel 2 is rotatably connected to the rotation shaft 1 through the rotation groove.

[0029] From the above, it can be seen that the cooperation between the rotating shaft 1, the moving wheel 2, the support plate 3 and the push handle frame 4 is used to form a vehicle that can travel in a narrow space, reducing the size of the transport vehicle. Correspondingly, it is convenient for this transport vehicle to travel in a narrow space, and there is no need for manual lifting, which makes the construction time-consuming and labor-intensive, and facilitates the staff to transport and use the hydraulic column.

[0030] Example 2

[0031] like Figure 1 、 Figure 2 、 Figure 3 As shown, the clamping installation mechanism includes a square chute 5 opened on the top of the support plate 3, one side of the inner wall of the square chute 5 is fixedly connected to a servo motor 501, and the output end of the servo motor 501 is fixedly connected to a threaded rod 502, and the threaded rod 502 is rotated and extended to the other side of the square chute 5 at one end away from the servo motor 501 to the other side of the square chute 5, and the inner middle position of the square chute 5 is fixedly connected to a limit plate 503, and the outer wall of the threaded rod 502 is located between the square chute 5 and the limit plate 503 and is threadedly connected to a threaded block 504, and a clamping plate 505 is fixedly installed on the top of the threaded block 504, and a sliding baffle 506 is connected to one side of the clamping plate 505;

[0032] The present invention is further specifically described in detail. The threaded rod 502 and the limiting plate 503 are rotatably arranged. The outer wall of the threaded block 504 and the inner wall of the square slide 5 are slidingly fitted. The bottom of the sliding baffle 506 and the top of the square slide 5 are slidingly fitted. The outer wall of the threaded rod 502 is located between the square slide 5 and the limiting plate 503 and is provided with a thread groove. The two thread grooves are arranged in opposite directions. The threaded rod 502 is threadedly connected to the threaded block 504 through the thread groove.

[0033] As can be seen from the above, when the staff transports the hydraulic column, they place the hydraulic column to be transported between the two clamping plates 505, and then rotate the servo motor 501 forward to rotate it. According to the effect of the opposite arrangement of the two thread grooves, the distance between the two clamping plates 505 can be reduced, so that the two clamping plates 505 clamp the outer wall of the hydraulic column. With the arrangement of this structure, when the staff transports the hydraulic column, the clamping plates 505 can be used to clamp the hydraulic column, thereby improving the stability of the hydraulic column during transportation and improving the work efficiency of the staff in transporting the hydraulic column.

[0034] When the transport vehicle is not in use, the servo motor 501 can be turned on to reduce the distance between the two clamping plates 505 to the shortest. At this time, the sliding baffle 506 can slide and fit with the top of the square chute 5 to protect the servo motor 501 and the threaded rod 502 inside the square chute 5, thereby avoiding corrosion damage to the servo motor 501 and the threaded rod 502, thereby improving the work efficiency of the staff in using the transport vehicle to transport the hydraulic column.

[0035] Furthermore, this design application is used to transport the hydraulic column, and the cooperation between the rotating shaft 1, the moving wheel 2, the support plate 3 and the push handle frame 4 is used to form a vehicle that can travel in a narrow space, reducing the size of the transport vehicle. Accordingly, it is convenient for the transport vehicle to travel in a narrow space, and there is no need for manual lifting, which makes the construction time-consuming and labor-intensive, and facilitates the staff to transport the hydraulic column.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
