Description

Technical Field

[0001] This utility model relates to the technical field of switchgear trolley transfer equipment, specifically to a transfer trolley slide rail with adjustable width. Background Technology

[0002] Switchgear is used to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes of a power system. The switchgear trolley is the core component installed inside the switchgear, and it needs to be replaced promptly if it malfunctions. During the replacement of the switchgear trolley, a transfer trolley is required for transportation. However, since different models of switchgear trolleys have different distances between their bottom rollers, the slide rails on the transfer trolley must be designed with adjustable width to accommodate different models of switchgear trolleys.

[0003] Currently, there are some transport trolleys with adjustable slide rail widths. However, most of them are manually adjustable, requiring the fixing bolts on the front and back sides of the slide rail to be loosened separately for adjustment. This makes it impossible to adjust the front and back sides synchronously and quickly, which is time-consuming, laborious, and inaccurate. Furthermore, transport trolleys with adjustable slide rails generally only have a few adjustment holes, which can only accommodate a few fixed width dimensions of switch cabinet trolleys, resulting in limited adjustment range and insufficient flexibility and adaptability. Utility Model Content

[0004] The purpose of this invention is to provide a width-adjustable transfer trolley slide rail, which can quickly adjust the distance between the slide rails to adapt to different models of switchgear trolleys and improve work efficiency.

[0005] This utility model includes a vehicle frame, on which a lifting platform that can move up and down along the vehicle frame is installed. The lifting platform has a load-bearing plate, and a slide rail for moving the handcart is installed on the upper side of the load-bearing plate. There are two slide rails, symmetrically arranged on the left and right sides of the load-bearing plate. One side of the load-bearing plate has a slide groove that runs through the upper and lower ends of the load-bearing plate and extends along the length of the load-bearing plate. A slide rail adjustment mechanism is installed on the lower side of the load-bearing plate. The slide rail adjustment mechanism includes a lead screw, on which a lead screw nut is sleeved and fixed to the load-bearing plate. A connecting plate is fixed to the inner end of the lead screw, and a connecting block is fixed to the connecting plate. The connecting block passes through the slide groove and is fixedly connected to the slide rail. On the connecting plate, located on the side of the lead screw, a slide rod is also fixed. The other end of the slide rod is slidably installed in a slide sleeve, which is fixed to the load-bearing plate.

[0006] With the above structure, when it is necessary to move switchgear trolleys of different widths, it is only necessary to rotate the lead screw to move the connecting plate left and right, thereby moving the slide rail connected to the connecting plate. This allows for the adjustment of the slide rail width to accommodate different switchgear trolleys. The structure is simple, easy to use, highly efficient, and precise.

[0007] Preferably, there are two of each of the sliding groove and the connecting block, which are symmetrically arranged on the front and rear sides of the load-bearing plate.

[0008] Preferably, there are two slide rods and two slide sleeves, symmetrically arranged on both sides of the lead screw.

[0009] Preferably, the slide bar and the lead screw are arranged parallel to each other.

[0010] Preferably, a limiting plate is fixed to the outer end of the slide bar.

[0011] Preferably, a handwheel is connected to the outer end of the lead screw.

[0012] Preferably, the slide rail adjustment mechanism has two sets, symmetrically arranged at the left and right ends of the load-bearing plate, and respectively connected to the slide rails located on the left and right sides of the load-bearing plate.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When it is necessary to move switchgear trolleys of different widths, simply rotate the lead screw to move the connecting plate left and right, thereby moving the slide rail connected to the connecting plate. This allows for adjustment of the slide rail width to accommodate different switchgear trolleys. The structure is simple, easy to use, highly efficient, and precise.

[0015] 2. The front and rear ends of the slide rail are fixed to the same connecting plate. The front and rear ends of the connecting plate are respectively provided with slide grooves and slide rods, which can ensure that the front and rear ends of the connecting rod move synchronously and are not prone to deviation. This prevents the slide rail from tilting due to inconsistent movement of the front and rear ends during the adjustment process, which would cause the slide rails on the left and right sides of the load-bearing plate to be non-parallel and make it difficult to align when moving the switch cabinet trolley.

[0016] 3. The slide rail adjustment mechanism has two sets, symmetrically arranged at the left and right ends of the load-bearing plate, and connected to the slide rails on the left and right sides of the load-bearing plate respectively; the position of the two slide rails can be adjusted independently, so that the switch cabinet trolley is always in the middle of the load-bearing plate. Compared with the structure that can only adjust the slide rail on one side, this structure is more reasonable and can prevent the switch cabinet trolley from being located on one side of the load-bearing plate after adjustment, causing the load-bearing plate to be eccentric and the force to be uneven.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The orientations mentioned in this specification are based on the orientation of the adjustable width transfer trolley slide rail of this utility model when it is working normally. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0024] Example 1:

[0025] like Figures 1 to 3 As shown, a width-adjustable transfer trolley slide rail includes a trolley frame 1, which is a rectangular frame welded from steel structural components. A lifting platform 2 that can move up and down along the trolley frame 1 is installed on the trolley frame 1. The lifting platform 2 is provided with a load-bearing plate 3. A slide rail 4 for moving the trolley is installed on the upper side of the load-bearing plate 3. The slide rail 4 has two symmetrically arranged on the left and right sides of the load-bearing plate 3. The distance between the two slide rails 4 is the same as the distance between the bottom rollers of the switch cabinet trolley 100 to be transferred. When it is necessary to move the switch cabinet trolley 100 to the transfer trolley, the two slide rails 4 are aligned with the bottom rollers of the switch cabinet trolley 100, so that the switch cabinet trolley 100 can be easily moved, saving time and effort.

[0026] The front end of the slide rail 4 extends out of the load-bearing plate 3, and a positioning pin 7 is fixed at the end. The positioning pin 7 can be inserted into the positioning hole on the switch cabinet housing. During the transfer process, the positioning pin 7 is positioned with the switch cabinet housing to ensure that the transfer trolley can be aligned with the switch cabinet housing. On the one hand, it can prevent the transfer trolley from moving laterally, and on the other hand, it can ensure the accuracy of the connection between the transfer trolley and the switch cabinet housing.

[0027] Furthermore, a sliding groove 5 is provided on one side of the load-bearing plate 3, extending through the upper and lower ends of the load-bearing plate 3. The sliding groove 5 extends along the length of the load-bearing plate 3. A slide rail adjustment mechanism 6 is installed on the lower side of the load-bearing plate 3. The slide rail adjustment mechanism 6 includes a lead screw 601, on which a lead screw nut 602 is sleeved. The lead screw nut 602 is fixed to the load-bearing plate 3. A connecting plate 603 is fixed to the inner end of the lead screw 601. A connecting block is fixed to the connecting plate 603. The connecting block passes through the sliding groove 5 and is fixedly connected to the slide rail 4. A sliding rod 604 is also fixed to the connecting plate 603, located on the side of the lead screw 601. The slide rod 604 is set parallel to the lead screw 601. The other end of the slide rod 604 is slidably installed in the slide sleeve 605, which is fixed to the load-bearing plate 3. A handwheel 607 is connected to the outer end of the lead screw 601. Rotating the handwheel 607 drives the lead screw 601 to rotate, thereby driving the connecting plate 603 and the slide rod 604 to move left and right. This causes the connecting block and the slide rail 4 to move left and right along the slide groove 5, thereby adjusting the distance between the two slide rails 4 to accommodate switch cabinet trolleys 100 of different widths. It should be noted that after the position of the slide rail 4 is adjusted, the slide rail 4 needs to be fixed to prevent it from moving.

[0028] Furthermore, two slide rails 5 and two connecting blocks are provided, symmetrically arranged on the front and rear sides of the load-bearing plate 3, so that the movement of the slide rail 4 is more stable and less prone to deviation.

[0029] Furthermore, two slide rods 604 and two slide sleeves 605 are provided, symmetrically arranged on both sides of the lead screw 601. The slide rod 604 guides the connecting plate 603 on one hand, and on the other hand, it supports the lead screw 601 on both sides, making the movement more stable and strengthening the overall mechanism to prevent the connecting plate 603 from deforming.

[0030] Furthermore, a limiting plate 606 is fixed to the outer end of the slide rod 604. When the limiting plate 606 moves to the outer end of the load-bearing plate 3, the slide rod 604 stops moving to prevent the slide rod 604 from derailing.

[0031] Example 2:

[0032] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the slide rail adjustment mechanism 6 is provided in two sets, symmetrically arranged at the left and right ends of the load-bearing plate 3, and respectively connected to the slide rails 4 on the left and right sides of the load-bearing plate 3; the positions of the two slide rails 4 can be adjusted independently, so that the switch cabinet trolley 100 is always in the middle of the load-bearing plate 3. Compared with the structure that can only adjust one side of the slide rail 4, this structure is more reasonable and less likely to cause the load-bearing plate 3 to be eccentric.

[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
