Description

Technical Field

[0001] This utility model relates to the field of ground tool transportation technology, and in particular to a ground tool transfer vehicle. Background Technology

[0002] Grounding switches, also known as grounding circuit breakers, are important electrical devices in power systems used to ensure the safety of equipment and personnel. They are widely used in substations, power plants, and other similar locations. During the installation, inspection, or maintenance of power equipment, it is often necessary to move grounding switches from different locations to meet operational needs. Grounding switch transport vehicles are specialized transport devices used for transporting grounding switches.

[0003] Currently, when transporting grounding cutters, it has been found that most existing transport vehicles directly and rigidly attach the grounding cutters to the support structure of the transport vehicle. When the transport vehicle moves to bumpy sections (gravel roads, rough roads), the grounding cutters will bounce on the support structure due to the bumps. When the bounced grounding cutters fall, they will directly hit the support structure. The connection between the grounding cutter and the support structure (mounting plate, back plate, or connecting rod, etc.) is prone to damage to both the grounding cutter and the support structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grounding chute transport vehicle, which solves the problem that existing grounding chute transport vehicles are prone to damage to the grounding chute or their own support structure when moving on bumpy roads.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The excavator transport vehicle includes;

[0007] Grounding switch is used to ensure the safety of personnel and equipment during the maintenance of electrical equipment;

[0008] The support mechanism, used to support the grounding switch, includes a support member, a support plate, and a buffer assembly. The support member is U-shaped and can bend and deform when subjected to pressure from above. The support plate is a plate-like structure made of stainless steel, and the support member is made of spring steel. Its material properties give it high toughness and allow it to bend. The support member can convert the weight of the grounding switch into a compressive force on the buffer assembly. When the transfer mechanism moves, it will bump, causing the grounding switch to jump up and down on the surface of the support member when the transfer mechanism moves to a bumpy section. When the grounding switch jumps, it will exert an impact force on the support member. The support member can transfer the impact force of the grounding switch to the buffer assembly through the support plate by bending and deforming itself. The buffer assembly can change its length after being compressed. When the length of the buffer assembly changes, it can reduce the impact force of the grounding switch on the support member. The deformation of the support member itself prevents the grounding switch from hitting the support member hard. The impact force of the grounding switch is transferred to the buffer assembly and absorbed by it through deformation and force dissipation, so as to avoid damage to the support member or the grounding switch from impact.

[0009] The pressing mechanism is used to fix the grounding switch. It includes a pressure plate, which is a plate-shaped structure made of stainless steel. The pressure plate can rotate along its central axis. The two ends of the pressure plate abut against the top surfaces of the two grounding switches respectively.

[0010] The transfer mechanism is used to install the support mechanism and can move on the ground. The connection between the support mechanism and the transfer mechanism is equipped with an elastic structure made of rubber. The elastic structure is used to prevent noise caused by friction between the end plate or support and the mounting rod.

[0011] Preferably, the transfer mechanism includes a base plate, which is a plate-shaped frame structure made of stainless steel tubing. All four corners of the bottom surface of the base plate are fixed with casters by screws, and the base plate and casters enable the transfer vehicle to move as a whole.

[0012] Preferably, the top surface of the base plate is fixedly connected to two support rods by welding, and the ends of the two support rods away from the base plate are rotatably connected to handles by means of a rotating shaft.

[0013] Preferably, two sets of mounting rods are fixedly connected between the two support rods by welding, with two mounting rods in each set. The ends of the two support rods away from the base plate are fixedly connected to a connecting rod by welding. Both the mounting rods and the connecting rods are rod-shaped structures made of stainless steel.

[0014] Preferably, the buffer mechanism includes end plate one and end plate two, both of which are plate structures made of stainless steel. Two support springs are fixedly connected between end plate one and end plate two by welding. Two damping rods are fixedly connected between end plate two and end plate one by welding. The two damping rods are located inside the two support springs respectively. The damping rods, together with the support springs, cause the buffer mechanism to shrink and shorten as a whole through their own compression deformation. The support springs and damping rods absorb the compressive force through their own deformation, thereby achieving the buffering effect.

[0015] Preferably, the support plate is fixedly connected to the bottom surface of the support member by welding, and the end of the support plate away from the support member is fixedly connected to the end plate by welding.

[0016] Preferably, a rubber pad is fixedly connected to the side of the support member away from the support plate by adhesive. The rubber pad is L-shaped and made of rubber. The support member and the side of the end plate two near the mounting rod are both fixedly connected by adhesive with an elastic structure. The side of the end plate two away from the support spring is fixedly connected by welding with a plug.

[0017] Preferably, there are eight support mechanisms. The eight support mechanisms are divided into four groups of two and installed on both sides of two sets of mounting rods. The support members are fixedly connected to the mounting rods by screws. Two through holes are opened on the side of the support member closest to the mounting rod. Two screw holes are opened on the surface of the upper mounting rod in each set of mounting rods. The through holes on the surface of the support member are aligned with the screw holes and the support member is fixed with screws. Four through holes are opened on the surface of the lower mounting rod in each set of mounting rods. Four plugs are inserted into the four through holes respectively.

[0018] Preferably, the pressing mechanism includes a cylindrical connector, the top surface of which is rotatably connected to a cylindrical connector via a damping bearing, and the end of the cylindrical connector away from the cylindrical connector is fixedly connected to the pressure plate. There are two pressing mechanisms, and the two cylindrical connectors are fixedly connected to the top surface of the upper mounting rod of the two sets of mounting rods by welding.

[0019] Preferably, the grounding switch includes a mounting frame and a connecting rod. The grounding switch is an existing technology and also includes a stationary contact, a moving contact, a grounding conductor, an operating handle, a transmission mechanism, and an insulating support. The connecting rod is a structure in the transmission mechanism. The mounting frame and the mounting rod are in contact with each other. The grounding switch is hung on the inside of the support member by its own weight. The mounting rod squeezes the mounting frame to limit the grounding switch and prevent the grounding switch from tilting and falling on the support mechanism due to its top-heavy nature. A grounding switch is placed on the top surface of each support mechanism. The end of the pressure plate is in contact with the top surface of the connecting rod in the grounding switch, and the rubber pad is in contact with the bottom surface of the connecting rod.

[0020] In practical use, when the transfer mechanism travels to bumpy sections, the grounding switch will bounce on the support mechanism. Since the support mechanism is in direct contact with the grounding switch and the support structure is small, the impact force from the vertical bounce of the grounding switch can easily damage the support or the connecting rod of the grounding switch. This application solves this problem by setting up a buffer mechanism to buffer the force on the grounding switch. The gravitational potential energy generated by the vertical bounce of the grounding switch is converted into a compressive force on the buffer mechanism through the support and support plate. The impact force is absorbed by the contraction and deformation of the support spring and damping rod, thus preventing damage to the grounding switch or the support. This allows the grounding switch to be transported on bumpy sections, solving the problem that existing grounding switch transfer vehicles are prone to damage to the grounding switch or its own support structure when moving on bumpy sections.

Detailed Implementation

[0029] This application provides a grounding chaff transport vehicle, which effectively solves the problem that existing grounding chaff transport vehicles are prone to damage to the grounding chaff or their own support structure when moving on bumpy roads.

[0030] Example 1

[0031] When transporting grounding cutters, existing grounding cutter transport vehicles often directly and rigidly attach the grounding cutters to the vehicle's support structure. When the transport vehicle moves to bumpy sections (gravel roads, rough roads), the grounding cutters bounce on the support structure due to the bumps. When the bounced grounding cutters fall, they directly impact the support structure, easily causing damage to the connection points between the grounding cutter and the support structure (mounting plate, back plate, or connecting rod, etc.).

[0032] To address the problems existing in the prior art, this utility model provides a ground tool transfer vehicle;

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the grounding switch transfer vehicle includes a grounding switch 100, a transfer mechanism 200, a support mechanism 300, and a pressing mechanism 400. The grounding switch 100 is used to ensure the safety of personnel and equipment during electrical equipment maintenance and is existing technology. The support mechanism 300 supports the grounding switch 100 and includes a support member 301, a support plate 304, and a buffer assembly. The support member 301 is U-shaped and can bend and deform when subjected to downward pressure (L1). The support plate 304 is made of stainless steel. The plate-like structure, with support member 301 made of spring steel, possesses high toughness and bendability due to its material properties. Support member 301 can convert the gravity of the grounding switch 100 into a compressive force on the buffer assembly. When the transfer mechanism 200 moves, it will bump, causing the grounding switch 100 to bounce up and down on the surface of support member 301 when the transfer mechanism 200 moves to a bumpy section. This bouncing of the grounding switch 100 will exert an impact force on support member 301, which can be absorbed by its own bending deformation. The impact force is transmitted to the buffer mechanism via the support plate 304. The buffer assembly, when compressed, can change its length. This change in length reduces the impact force of the grounding switch 100 on the support member 301. The deformation of the support member 301 prevents the grounding switch 100 from colliding directly with it. Through deformation-based force dissipation, the impact force of the grounding switch 100 is transmitted to and absorbed by the buffer mechanism, preventing damage to the support member 301 or the grounding switch 100 from the impact. The pressing mechanism 400 is used to fix the grounding switch 100, and includes... The pressure plate 403 is a plate-shaped structure made of stainless steel. The pressure plate 403 can rotate along its central axis. The two ends of the pressure plate 403 abut against the top surfaces of the two grounding switches 100 respectively. The transfer mechanism 200 is used to install the support mechanism 300, which can move on the ground. The part where the support mechanism 300 is connected to the transfer mechanism 200 is provided with an elastic structure 302. The elastic structure 302 is made of rubber and is used to prevent noise from being generated by the friction between the end plate 306 or the support 301 and the mounting rod 205.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the transfer mechanism 200 includes a base plate 201, which is a plate-shaped frame structure made of stainless steel tubing. The four corners of the bottom surface of the base plate 201 are fixed with casters 202 by screws. The base plate 201 and the casters 202 together enable the transfer vehicle to move as a whole.

[0035] like Figure 2 and Figure 3As shown, two support rods 203 are fixedly connected to the top surface of the base plate 201 by welding. The ends of the two support rods 203 away from the base plate 201 are rotatably connected to handles 204 by means of a rotating shaft.

[0036] like Figure 3 As shown, two sets of mounting rods 205 are fixedly connected between the two support rods 203 by welding. Each set of mounting rods 205 consists of two rods. The ends of the two support rods 203 away from the base plate 201 are fixedly connected to a connecting rod by welding. Both the mounting rods 205 and the connecting rods are rod-shaped structures made of stainless steel.

[0037] like Figure 4 and Figure 5 As shown, the buffer mechanism includes end plate 1 305 and end plate 2 306. Both end plate 1 305 and end plate 2 306 are plate structures made of stainless steel. Two support springs 308 are fixedly connected to end plate 1 305 and end plate 2 306 by welding. Two damping rods 309 are fixedly connected to end plate 2 306 and end plate 1 305 by welding. The two damping rods 309 are located inside the two support springs 308. The damping rods 309, together with the support springs 308, cause the buffer mechanism to shrink and shorten as a whole through their own compression deformation. The support springs 308 and damping rods 309 absorb the compressive force through their own deformation, thus achieving the buffering effect.

[0038] like Figure 4 and Figure 5 As shown, the support plate 304 is fixedly connected to the bottom surface of the support member 301 by welding, and the end of the support plate 304 away from the support member 301 is fixedly connected to the end plate 305 by welding.

[0039] like Figure 4 and Figure 5 As shown, a rubber pad 303 is fixedly connected to the side of the support member 301 away from the support plate 304 by adhesive. The rubber pad 303 is L-shaped and made of rubber. The support member 301 and the side of the end plate 2 306 near the mounting rod 205 are both fixedly connected to an elastic structure 302 by adhesive. The side of the end plate 2 306 away from the support spring 308 is fixedly connected to a plug 307 by welding.

[0040] like Figure 4 and Figure 5As shown, there are eight support mechanisms 300. The eight support mechanisms 300 are divided into four groups of two and installed on both sides of the two groups of mounting rods 205. The support member 301 is fixedly connected to the mounting rod 205 by screws. The support member 301 has two through holes on the side near the mounting rod 205. The upper mounting rod 205 in each group of mounting rods 205 has two screw holes. The through holes on the surface of the support member 301 are aligned with the screw holes and fixed to the support member 301 with screws. The lower mounting rod 205 in each group of mounting rods 205 has four through holes. Four plugs 307 are inserted into the four through holes respectively.

[0041] like Figure 2 and Figure 6 As shown, the pressing mechanism 400 includes a cylindrical connector 401. The top surface of the cylindrical connector 401 is rotatably connected to a cylindrical connector 402 via a damping bearing. The end of the cylindrical connector 402 away from the cylindrical connector 401 is fixedly connected to the pressure plate 403. There are two pressing mechanisms 400. The two cylindrical connectors 401 are fixedly connected to the top surface of the upper mounting rod 205 of the two sets of mounting rods 205 by welding.

[0042] like Figure 1 and Figure 2 As shown in the figure, the grounding switch 100 includes a mounting frame 101 and a connecting rod. The grounding switch 100 is a prior art technology, and it also includes a stationary contact, a moving contact, a grounding conductor, an operating handle, a transmission mechanism, and an insulating support. The connecting rod is a structure in the transmission mechanism. The mounting frame 101 and the mounting rod 205 are in contact with each other. The grounding switch 100 is hung on the inside of the support member 301 by its own weight. The mounting rod 205 presses against the mounting frame 101 to provide a simple limit on the grounding switch 100, preventing the grounding switch 100 from tilting and falling on the support mechanism 300 due to its top-heavy nature. Each set of support mechanisms 300 has a grounding switch 100 placed on its top surface. The end of the pressure plate 403 is in contact with the top surface of the connecting rod in the grounding switch 100, and the rubber pad 303 is in contact with the bottom surface of the connecting rod.

[0043] This application sets up a transfer mechanism 200, and sets up eight support mechanisms 300 on the transfer mechanism 200. The eight support mechanisms 300 can support four grounding switches 100. The top surface of the base plate 201 can also place two grounding switches 100, so that this application can place six grounding switches 100 at one time. While the transportation efficiency is high, the six grounding switches 100 do not interfere with each other and do not need to be stacked, avoiding the grounding switches 100 being squeezed and damaged (their insulating support is a ceramic structure, which is easily damaged by impact).

[0044] In practical use, when the transfer mechanism 200 travels on bumpy roads, the grounding switch 100 will bounce on the support mechanism 300. Since the support mechanism 300 is in direct contact with the grounding switch 100, and the support member 301 is relatively small, the impact force from the vertical bounce of the grounding switch 100 can easily damage the support member 301 or the connecting rod of the grounding switch 100. This application solves this problem by setting a buffer mechanism to buffer the force on the grounding switch 100. The gravitational potential energy generated by the vertical bounce of the grounding switch 100 is converted into a compressive force on the buffer mechanism through the support member 301 and the support plate 304. The impact force is absorbed by the contraction and deformation of the support spring 308 and the damping rod 309, thus preventing damage to the grounding switch 100 or the support member 301. This allows the grounding switch 100 to be transported on bumpy roads, solving the problem that existing grounding switch transfer vehicles are prone to damage to the grounding switch or its own support structure when moving on bumpy roads.

[0045] The two grounding switches 100 placed on the base plate 201 can be placed directly on the top surface of the base plate 201 through the mounting bracket 101. Their connecting rods do not need to contact the base plate 201. The mounting bracket 101 is a stainless steel structure, and the base plate 201 is also a stainless steel structure, which is not easily damaged by impact.

[0046] The above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
