Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and in particular to a lifting type indoor substation equipment transfer platform. Background Art

[0002] With the acceleration of urbanization, especially in urban underground or high-rise buildings, the installation and maintenance of substation equipment are facing increasing challenges. Due to the limited space and complex equipment distribution of indoor substations, large lifting and transportation equipment cannot be used, manual handling is time-consuming and labor-intensive, and may also cause damage to equipment or injury to personnel. In order to improve efficiency, reduce risks, and adapt to narrow and enclosed spaces, lifting equipment transfer devices came into being. When placing power equipment on the lifting equipment transfer device, since the transfer device is usually equipped with multiple rollers to facilitate the transportation of power equipment, and the power equipment is large in size and heavy in weight, it may slide or tilt due to unstable center of gravity when placed, or even fall from the transfer device.

[0003] The lifting equipment transfer device in the prior art, such as a lifting roller platform and a transportation system disclosed in the Chinese patent document with authorization announcement number CN208022225U, during the lifting process of the lifting roller platform and the transportation system, the upper surface of the supporting part is located above the roller, which can ensure that the upper surface of the supporting part is in contact with the material, thereby providing a relatively stable support for the material, effectively preventing the material from slipping, and improving safety; when the lifting bracket is descending, when the lower surface of the first limit part is in contact with the upper surface of the base, the inner frame is driven to move downward relative to the outer frame, so that the upper surface of the supporting part is located below the roller. At this time, the upper surface of the roller is in contact with the material, which is convenient for transporting the material.

[0004] However, during use, the above-mentioned lifting roller platform and transportation system in the prior art can only make the upper surface of the roller contact with the material and unlock the transportation function of the roller when the lifting bracket is lowered to the first limit portion and the lower surface is in contact with the upper surface of the base, that is, when the lifting bracket is lowered to the lowest position. The unlocking operation of the roller depends on the lifting bracket being raised to a specific height, which limits the flexibility during operation and is difficult to quickly adjust according to actual conditions. Summary of the invention

[0005] The present invention provides a lifting type indoor substation equipment transfer platform, aiming to solve the problem that the unlocking operation of the rollers in the lifting roller platform and the transportation system in the related art depends on the lifting height of the lifting bracket and the operation flexibility is poor.

[0006] The present invention provides a lifting type indoor substation equipment transfer platform adopts the following technical solutions: A lifting type indoor substation equipment transfer platform comprises a base, a walking device arranged at the lower end of the base, a lifting mechanism arranged at the upper end of the base, and a bearing mechanism arranged at the upper end of the lifting mechanism, wherein the bearing mechanism comprises: The bearing unit comprises a plurality of rollers distributed front and back and used to bear the power equipment on the upper surface, and a locking member which is assembled on the ends of the plurality of rollers and used to lock the plurality of rollers and is movable left and right, wherein the end of the rotating shaft of each roller has a card block, and the locking member has a card slot corresponding to each roller, and the card slot is used to insert the card block to limit the rotation of the roller; A main frame is installed on the upper end of the lifting mechanism, and the bearing unit is arranged on the main frame; The detector comprises a movable plate which is assembled on a main frame and moves forward and backward, and two detection blocks which are assembled on the main frame and move upward and downward and are distributed forward and backward. The movable plate is provided with limit grooves corresponding to the detection blocks for accommodating the detection blocks, and guide grooves which are connected with the locking members and are used to drive the locking members to move left and right. The upper surface of each detection block forms a detection surface for placing the electric equipment. When the detection surfaces of the two detection blocks are subjected to the pressure of the electric equipment and move downward, the two detection blocks jointly push the movable plate forward, so that the movable plate drives the locking members to move to the card slot and disengage the card block through the guide groove, thereby enabling the roller to rotate.

[0007] By adopting the above technical scheme, the independent locking and unlocking of the roller is realized through the linkage design of the detector and the locking piece, which is no longer dependent on the lifting height of the lifting bracket, thereby improving the flexibility of operation and allowing the roller to be automatically locked and unlocked according to the placement of the power equipment at different heights. When the power equipment has not been placed stably, the roller is in a locked state, providing stable support for the power equipment and preventing the power equipment from sliding or tilting on the roller when it has not been placed stably. After the power equipment is placed stably, the roller is in an unlocked state, which is convenient for the roller to transport the power equipment, ensuring the stability of the power equipment at different stages and reducing operational risks.

[0008] Furthermore, the two locking members are symmetrically distributed on the left and right sides of the plurality of rollers, and correspond to the blocks on the left and right ends of the rotating shaft respectively.

[0009] By adopting the above technical solution, by symmetrically arranging the locking pieces on the left and right sides of the roller, a balanced locking force is provided, the reliability of locking is improved, and the safety of the power equipment during transportation is ensured.

[0010] Furthermore, a return spring is provided between each detection block and the main frame, and the return spring is used to apply elastic force to the detection block so that the detection block moves upward until the detection surface is located above the upper surface of the roller.

[0011] Furthermore, a groove is provided on the front side of the detection block, and the movable plate has a passive inclined surface extending into the groove, and the passive inclined surface is inclined downward from front to back. A push block for abutting the passive inclined surface is provided on the upper groove wall of the groove, and the push block is connected to the detection block through a first spring. A push space for accommodating the push block is reserved between the passive inclined surface and the groove, and the first spring is used to apply elastic force to the push block to move the push block forward, thereby pushing the movable plate to move forward.

[0012] Furthermore, the guide groove is inclined forward from the roller toward the locking member, and the locking member is provided with a guide block movably assembled in the guide groove.

[0013] Furthermore, an unlocking groove is provided on the rear side surface of the detection block at the same height as the pushing block, and the unlocking groove is used to accommodate the moving plate to allow the moving plate to move forward.

[0014] Furthermore, the bearing mechanism also includes an extension frame that is assembled on the main frame for forward and backward movement, and two bearing units are arranged on the extension frame. The bearing unit on the extension frame is set as a main bearing unit, and the bearing unit on the main frame is set as a secondary bearing unit. The two secondary bearing units are symmetrically distributed on the left and right sides of the main bearing unit.

[0015] With the above technical solution, the extension frame is an extended part of the bearing mechanism, which is used to realize the extension function of the transfer platform, so that the transfer platform can better dock with the unloading area, and facilitate the direct transfer of the power equipment to the target table.

[0016] Furthermore, a locking spring is arranged between the locking piece of the auxiliary bearing unit and the extension frame, and the locking spring is used to apply elastic force to the locking piece to make the locking piece move away from the roller, thereby disengaging the slot and the block to unlock the roller, and a pressure plate corresponding to each auxiliary bearing unit is arranged on the main frame, and the pressure plate is used to press the locking piece to make the locking piece close to the roller, thereby cooperating with the slot and the block to lock the roller.

[0017] By adopting the above technical solution, when the extension frame is not fully extended, the pressure plate pushes the locking member to lock the rollers of the sub-bearing unit, thereby ensuring the stable placement of the power equipment when the extension frame transports the power equipment forward. When the extension frame is fully extended, the locking spring drives the locking member to unlock the rollers of the sub-bearing unit, thereby facilitating the rollers to transport the power equipment and ensuring the stability of the power equipment at different stages.

[0018] Furthermore, the extension frame includes a mounting plate for mounting the auxiliary bearing unit, and a connecting plate located at the front end of the mounting plate for connecting the two mounting plates. The main frame is provided with a frame groove for accommodating the extension frame. When the extension frame is retracted into the frame groove, the connecting plate can push the movable plate backward to reset the movable plate.

[0019] By adopting the above technical solution, through the mechanical linkage design of the connecting plate and the movable plate, when the extension frame is retracted, the connecting plate can automatically push the movable plate backward to realize the resetting operation of the movable plate. No additional power device or complex control logic is required, which simplifies the equipment structure and improves the convenience and efficiency of operation.

[0020] Furthermore, the front end of the pressure plate has a reset pressure surface which is inclined forward from the auxiliary bearing unit toward the pressure plate, and the reset pressure surface is used to abut against the locking member to push the locking member close to the roller.

[0021] The beneficial effects of a lifting type indoor substation equipment transfer platform provided by the present invention are as follows: through the design of an extension frame, the bearing mechanism is expanded to realize the extension function of the transfer platform, so that the transfer platform can better dock with the unloading area, and it is convenient to transfer the power equipment directly to the target table; through the linkage design of the detector and the locking piece, the independent locking and unlocking of the rollers are realized, which is no longer dependent on the lifting height of the lifting bracket, and the flexibility of operation is improved, and the rollers are allowed to be automatically locked and unlocked according to the placement of the power equipment at different heights, so that when the power equipment is not placed stably, the rollers are in a locked state, providing stable support for the power equipment, preventing the power equipment from sliding or tilting on the rollers when it is not placed stably, and after the power equipment is placed stably, the rollers are in an unlocked state, which is convenient for the rollers to transport the power equipment, and the rollers of the main bearing unit and the auxiliary bearing unit are unlocked separately at different stages, ensuring the stability of the power equipment at different stages and reducing operational risks.

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 6 As shown, and refer to Figure 1 In the position shown in the figure, the embodiment of the lifting type indoor substation equipment transfer platform of the present invention comprises a base 10, a traveling device 110, a lifting mechanism 120, and a bearing mechanism 20. The traveling device 110 is arranged at the lower end of the base 10, and is used to enable the transfer platform to move horizontally indoors; the lifting mechanism 120 is arranged at the upper end of the base 10, and is used to lift the bearing mechanism 20 and the power equipment thereon to a desired height; the bearing mechanism 20 is arranged at the upper end of the lifting mechanism 120, and is used to place the power equipment to be transported.

[0031] like Figure 1 and Figure 2 As shown, the bearing mechanism 20 includes a main frame 220, an extension frame 240, a bearing unit, and a detector 230. The main frame 220 is fixedly mounted on the upper end of the lifting mechanism 120. The main frame 220 is the main structure of the bearing mechanism 20, provides support for the bearing unit and the extension frame 240, and transfers the weight to the base 10 and the lifting mechanism 120; the extension frame 240 is assembled on the main frame 220 for forward and backward movement, and can be extended forward relative to the main frame 220. The extension frame 240 is an extension part of the bearing mechanism 20, which is used to realize the extension function of the transfer platform, so that the transfer platform can better dock with the unloading area, and facilitate the direct transfer of the power equipment to the target table; the bearing unit is arranged on the main frame 220 and the extension frame 240, and is used to carry and transport the power equipment; the detector 230 is arranged on the main frame 220, and is used to detect whether the power equipment is placed stably.

[0032] A bearing unit is provided on the main frame 220, and a frame slot 222 for accommodating the extension frame 240 is provided at a position other than the position where the bearing unit is installed. Two bearing units are provided on the extension frame 240, and the extension frame 240 includes a mounting plate 241 for mounting the bearing unit, and a connecting plate 242 located at the front end of the mounting plate 241 for connecting the two mounting plates 241. The bearing unit on the extension frame 240 is set as the secondary bearing unit 212, and the bearing unit on the main frame 220 is set as the main bearing unit 211. The two secondary bearing units 212 are symmetrically distributed on the left and right sides of the main bearing unit 211.

[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, each bearing unit includes a plurality of rollers 30 distributed front and back and used to bear power equipment on the upper surface, and a locking member 40 movably assembled at the ends of the plurality of rollers 30 for locking the plurality of rollers 30. The ends of the rotating shafts 310 of each roller 30 are provided with a clamping block 320, and the locking member 40 has a clamping slot 410 corresponding to each roller 30, and the clamping slot 410 is used to insert the clamping block 320 to limit the rotation of the roller 30.

[0034] In the main bearing unit 211, two locking members 40 are symmetrically distributed on the left and right sides of the plurality of rollers 30, and correspond to the blocks 320 at the left and right ends of the rotating shaft 310, respectively. When the locking member 40 is away from the roller 30, the locking member 40 can move to the card slot 410 to cooperate with the card block 320 to limit the rotation of the roller 30, so that the roller 30 can provide stable support for the power equipment, and prevent the power equipment from sliding or tilting on the roller 30 when it is not placed stably. When the locking member 40 is close to the roller 30, the locking member 40 can move to the card slot 410 to disengage from the card block 320, so that the roller 30 can rotate freely, so that the roller 30 can transport the power equipment.

[0035] In the secondary bearing unit 212, the locking members 40 are distributed on one side of the plurality of rollers 30 close to the main bearing unit 211, and correspond to the block 320 at one end of the rotating shaft 310 close to the main bearing unit 211. The main frame 220 is provided with a pressing plate 221 corresponding to each secondary bearing unit 212, and the pressing plate 221 is used to press the locking member 40 of the secondary bearing unit 212 to make the locking member 40 close to the roller 30, and the locking member 40 can move to the card slot 410 to cooperate with the block 320 to limit the rotation of the roller 30, so that the roller 30 provides stable support for the power equipment, and prevents the power equipment from sliding or tilting on the roller 30 when it is not placed stably. A locking spring 430 is arranged between the locking member 40 and the extension frame 240. The locking spring 430 is used to apply elastic force to the locking member 40 to make the locking member 40 move away from the roller 30. The locking member 40 can move to the slot 410 and disengage from the block 320 so that the roller 30 can rotate freely, thereby enabling the roller 30 to transport the electrical equipment.

[0036] The front end of the pressure plate 221 has a reset pressure surface inclined forward from the auxiliary bearing unit 212 toward the pressure plate 221. The reset pressure surface is used to abut the locking piece 40 of the auxiliary bearing unit 212 when the extension frame 240 is retracted into the frame groove 222 to push the locking piece 40 close to the roller 30, thereby locking the roller 30 of the auxiliary bearing unit 212.

[0037] like Figures 2 to 5 As shown, the detector 230 includes a moving plate 50 assembled on the main frame 220 for front-to-back movement, and two detection blocks 60 assembled on the main frame 220 for up-down movement and distributed front-to-back.

[0038] The movable plate 50 is provided with a limit groove 510 corresponding to each detection block 60 for accommodating the detection block 60, and a guide groove 520 connected to the locking member 40 for driving the locking member 40 of the main bearing unit 211 to move left and right. The guide groove 520 is inclined forward from the roller 30 to the locking member 40, and the locking member 40 of the main bearing unit 211 is provided with a guide block movably assembled in the guide groove 520, so that when the movable plate 50 moves forward, the locking member 40 can be driven to approach the roller 30 through the guide groove 520 to unlock the roller 30 of the main bearing unit 211; when the movable plate 50 moves backward, the locking member 40 can be driven to move away from the roller 30 through the guide groove 520 to lock the roller 30 of the main bearing unit 211.

[0039] Two detection blocks 60 are located at the rear of the main frame 220. The upper surface of each detection block 60 forms a detection surface for placing electrical equipment. A reset spring 610 is arranged between each detection block 60 and the main frame 220, and the reset spring 610 is used to apply elastic force to the detection block 60 so that the detection block 60 moves up to the detection surface above the upper surface of the roller 30. A groove 620 is provided on the front side of each detection block 60, and the movable plate 50 has a passive inclined surface 530 extending into the groove 620, and the passive inclined surface 530 is inclined downward from front to back. A push block 630 for abutting the passive inclined surface 530 is arranged on the upper groove wall of the groove 620, and the push block 630 is connected to the detection block 60 through a first spring 631. A pushing space for accommodating the pushing block 630 is reserved between the passive inclined surface 530 and the groove 620. The first spring 631 is used to apply elastic force to the pushing block 630 to move the pushing block 630 forward, thereby pushing the moving plate 50 forward. An unlocking groove 640 is provided on the rear side surface of the detection block 60 at the same height as the pushing block 630. The unlocking groove 640 is used to accommodate the moving plate 50 to allow the moving plate 50 to move forward.

[0040] It should be noted that when the extension frame 240 is retracted into the frame groove 222, the connecting plate 242 can push the movable plate 50 backward to reset the movable plate 50, thereby realizing the resetting operation of the movable plate 50 without the need for an additional power device, simplifying the equipment structure, and improving the convenience and efficiency of operation.

[0041] The working process of the embodiment of the lifting type indoor substation equipment transfer platform of the present invention includes the following steps: The first step is the initial state. The bearing mechanism 20 is in a retracted state, and the extension frame 240 is retracted into the frame slot 222 of the main frame 220. The main bearing unit 211 and the auxiliary bearing unit 212 are both in a locked state. The slots 410 of the locking member 40 cooperate with the blocks 320 on the rotating shaft 310 to limit the rotation of the roller 30, ensuring that the platform remains stable in the initial state to provide stable support for electrical equipment that is not placed stably. The two detection blocks 60 of the detector 230 are in an upward state under the action of the reset spring 610, and the detection surface is located above the upper surface of the roller 30, waiting for the placement of the electrical equipment.

[0042] The second step is to place the equipment. The operator places the power equipment on the rollers 30 of the main bearing unit 211 and the auxiliary bearing unit 212. The detection surface of the detection block 60 moves downward under the pressure of the power equipment, driving the push block 630 to move downward to abut against the passive inclined surface 530, compressing the first spring 631, so that the push block 630 enters the push space when moving downward. When the power equipment is not placed stably, only one of the detection blocks 60 can move down to the push block 630 to enter the push space, and the unlocking slot 640 is opposite to the moving plate 50, and the unlocking slot 640 of the other detection block 60 is staggered in height with the moving plate 50, preventing the moving plate 50 from moving forward. After the power equipment is placed stably, the other detection block 60 moves down to the unlocking slot 640 and is opposite to the movable plate 50. At this time, the two unlocking slots 640 are opposite to the movable plate 50, allowing the movable plate 50 to move forward. The elastic force of the first spring 631 is released, and the movable plate 50 is pushed forward by the push block 630. The movable plate 50 drives the locking piece 40 to approach the roller 30 through the guide slot 520 to unlock the roller 30 of the main bearing unit 211, so that the main bearing unit 211 enters the unlocked state, and the auxiliary bearing unit 212 still remains in the locked state.

[0043] The third step is to extend the platform. The operator controls the extension frame 240 to extend forward so that it can dock with the unloading area. When the extension frame 240 extends forward, the main supporting unit 211 is in an unlocked state to avoid affecting the extension frame 240 in transporting the power equipment forward. The auxiliary supporting unit 212 is in a locked state to ensure the stable placement of the power equipment when the extension frame 240 transports the power equipment forward.

[0044] The fourth step is equipment transportation. When the extension frame 240 is fully extended, the pressure plate 221 is disengaged from the locking piece 40 of the auxiliary bearing unit 212, and the elastic force of the locking spring 430 is released, so that the locking piece 40 is away from the roller 30 to unlock the roller 30 of the auxiliary bearing unit 212, so that the auxiliary bearing unit 212 enters an unlocked state, allowing the roller 30 to rotate freely, and the operator pushes the power equipment forward along the roller 30 to the unloading area.

[0045] The fifth step is to retract the platform. After the transfer of the power equipment is completed, the operator controls the extension frame 240 to be retracted into the frame slot 222. The connecting plate 242 pushes the movable plate 50 to move backward, so that the locking piece 40 of the main bearing unit 211 is reset and locks the roller 30. The locking piece 40 of the auxiliary bearing unit 212 is reset to close to the roller 30 under the push of the pressure plate 221 to lock the roller 30 of the auxiliary bearing unit 212. The platform returns to its initial state and waits for the next transfer operation.

[0046] In this way, the embodiment of the lifting type indoor substation equipment transfer platform of the present invention expands the bearing mechanism 20 through the design of the extension frame 240, realizes the extension function of the transfer platform, enables the transfer platform to better dock with the unloading area, and facilitates the direct transfer of the power equipment to the target table; and also realizes the independent locking and unlocking of the roller 30 through the linkage design of the detector 230 and the locking member 40, which no longer depends on the lifting height of the lifting bracket, improves the flexibility of operation, and allows the roller 30 to be automatically locked and unlocked according to the placement of the power equipment at different heights, so that when the power equipment is not placed stably, the roller 30 is in a locked state, providing stable support for the power equipment, preventing the power equipment from sliding or tilting on the roller 30 when it is not placed stably, and after the power equipment is placed stably, the roller 30 is in an unlocked state, which is convenient for the roller 30 to transport the power equipment, and realizes that the rollers 30 of the main bearing unit 211 and the auxiliary bearing unit 212 are unlocked at different stages, ensuring the stability of the power equipment at different stages and reducing operational risks.

[0047] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
