Description

Technical Field

[0001] This invention relates to the field of equipment conveying technology, specifically to an equipment conveying device within a multi-compartment substation system. Background Technology

[0002] Multi-compartment prefabricated substations often have limited internal space and restricted turning radii. Equipment such as GIS systems are large and irregularly shaped, necessitating route constraints for transport and placement within the substation, typically requiring the use of ground guide channels or reserved walkways. Existing equipment transport devices often employ guide wheels or guide blocks in conjunction with guide channels to achieve route constraints, but these methods still have shortcomings in actual transport processes. On the one hand, the guide wheels and guide troughs lack reliable lifting switching and positioning retention structures for entry, disengagement and guidance state switching. Vibration and impact caused by crossing troughs, turning or uneven ground can easily lead to guide failure, yaw interference or jamming, affecting the stability and safety of the conveying. On the other hand, the equipment needs stable positioning and clamping during the conveying process to prevent relative slippage, posture changes or collisions. However, existing clamping methods mostly rely on external fastening or friction clamping, which are prone to backing and loosening due to vibration. Furthermore, they are not adaptable to the clamping positions of different equipment specifications, making it difficult to balance conveying reliability and positioning efficiency. Summary of the Invention

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, this embodiment provides a multi-compartment substation equipment conveying device, including a frame 1, casters 2 disposed at the bottom of the frame, a support platform 3 for carrying the equipment, and a lifting mechanism 4 for driving the support platform to rise and fall; characterized in that it further includes: at least one guide component 5 disposed at the bottom of the frame 1 and cooperating with a guide groove in the prefabricated compartment floor; and a clamping mechanism 6 disposed on the support platform 3, the clamping mechanism 6 including a clamping component 61 and a backstop component 62 for limiting the clamping state of the clamping component 61; wherein, the clamping component 61 includes clamping members 611 disposed opposite to each other and a pressing member 612 abutting against the lower part of the equipment, the pressing member 612 moves under the action of the equipment's gravity and drives the two clamping members 611 to rotate towards each other to clamp the equipment; the backstop component 62 is located inside the clamping component 61 and cooperates with the pressing member 612 to limit the backflow of the pressing member 612 in the clamping state.

[0019] In use, first push the device into the prefabricated compartment, aligning the guide component 5 at the bottom of the frame 1 with the guide groove area on the floor of the prefabricated compartment. The cooperation between the guide component 5 and the ground guide groove constrains the travel path, reducing the risk of collision during transportation in narrow passages. Then, adjust the height of the support platform 3 using the lifting mechanism 4, positioning the equipment in the clamping area above the support platform 3. Slowly lower the lower part of the equipment onto the clamping member 612 of the clamping component 61. The equipment's own weight acts on the clamping member 612, causing it to shift and thus driving the clamping member 611 to rotate in opposite directions, achieving rapid clamping of the equipment. After clamping, the anti-reverse component 62 cooperates with the clamping member 612 to form an anti-reverse lock, reducing the loosening of the clamping member 612 due to transportation vibration or reverse impact, thereby maintaining a stable clamping state. When it is necessary to release the equipment, unlock the anti-reverse component 62 to release the anti-reverse restriction, completing the unlocking and unloading.

[0020] like Figures 1 to 5 As shown, each guide assembly 5 includes a support 51, a guide 52, and a connecting rod assembly 53. The support 51 is fixedly installed at the bottom end of the frame 1 and includes an L-shaped support base 511 and two opposing ear plates 512. The support base 511 includes a vertical plate 5111 and a horizontal plate 5112. A movable groove is formed in the middle of the vertical plate 5111, and the gap between the movable groove and the two ear plates 512 is correspondingly set to provide swing space for the L-shaped rod 533.

[0021] The guide member 52 is movably disposed within the guide hole opened in the horizontal plate 5112. The guide member 52 includes a guide block 521 and a guide wheel 522 rotatably connected to the bottom end of the guide block 521 via an axle. The guide wheel 522 is used to cooperate with the prefabricated cabin ground guide groove, and the guide block 521 is used to support the guide wheel 522 and forms a hinge with the bottom end of the connecting rod assembly 53.

[0022] The linkage assembly 53 includes a first link 531, a second link 532, an L-shaped rod 533, and a connecting rod 534. The upper end of the first link 531 is hinged to the two ear plates 512, the lower end of the second link 532 is hinged to the guide block 521, and one end of the connecting rod 534 is hinged to the lower end of the first link 531 and the upper end of the second link 532 on the same shaft, and the other end is hinged to the L-shaped rod 533, thereby forming a linkage mechanism that converts the swing of the L-shaped rod 533 into the lifting and lowering of the guide wheel 522.

[0023] A receiving groove 11 is provided at the bottom of the frame 1, and a fan-shaped guide groove 12 is provided on the frame above the receiving groove 11. The right-angle inflection point of the L-shaped rod 533 is movably connected to the vertical plate 5111 via a hinge shaft and is located in the movable groove; the free end of the L-shaped rod 533 passes through the receiving groove 11 and is provided with a movable part 535. When the L-shaped rod 533 swings within the space defined by the receiving groove 11 and the movable groove, the connecting rod 534 drives the first connecting rod 531 and the second connecting rod 532 to move together, so that the guide block 521 and the guide wheel 522 switch between the raised position and the lowered position; at the same time, the movable part 535 reciprocates in the fan-shaped guide groove 12 to constrain the swing trajectory and limit position of the L-shaped rod 533, thereby realizing the switching of the guide wheel 522's lifting and lowering.

[0024] The movable component 535 is located in the mounting groove at the free end of the L-shaped rod 533. The movable component 535 includes a guide post 5351, a sliding part 5352, and an elastic component 5353. The sliding part 5352 includes a slider 53521 sleeved on the guide post 5351 and a follower pin 53522 that reciprocates within the fan-shaped guide groove 12. One end of the elastic component 5353 is connected to the slider 53521, and the other end is connected to the inner wall of the mounting groove, giving the slider 53521 and the follower pin 53522 a pre-tightening tendency toward the fan-shaped guide groove 12. The fan-shaped guide groove 12 has slots 13 at both ends. The follower pin 53522 cooperates with the slots 13 to achieve a limit, thereby limiting the extreme stroke of the guide wheel 522 in the raised and lowered positions, and maintaining the position when it is in place, reducing the risk of mis-switching of the guide wheel 522 due to vibration.

[0025] like Figure 6 and Figure 8-10 As shown, the clamping assembly 61 includes a base 613 and a support seat 614 disposed at the top of the base 613. The clamping members 611 are arranged opposite each other, each clamping member 611 including a mounting block 6111 and an arc-shaped clamping arm 6112. The support seat 614 has openings 6141 on both sides. The mounting block 6111 is mounted in the openings 6141 via a pivot, allowing the arc-shaped clamping arm 6112 to rotate around the pivot. A limiting post 6142 is provided at the edge of the openings 6141. The axis of the limiting post 6142 is parallel to the axis of the pivot, used to limit the rotational stroke and constrain the attitude of the arc-shaped clamping arm 6112, preventing interference or instability of the clamping posture due to excessive rotation of the clamping arm.

[0026] like Figure 9 , Figure 10 and Figure 12 As shown, a rectangular groove 6143 is formed on the top of the bearing seat 614, and the clamping member 612 is slidably disposed in the rectangular groove 6143. A connecting ear plate 616 is provided at the bottom end of the clamping member 612. The connecting ear plate 616 is hinged to the mounting blocks 6111 on both sides through a connecting rod 615, so as to convert the sliding displacement of the clamping member 612 into the opposite rotation of the clamping members 611 on both sides.

[0027] To simultaneously meet the arrangement requirements of the guiding and anti-rollover components, a T-shaped slide rail 6144 is provided on one side of the inner wall of the rectangular groove 6143, and a fixing groove 6145 is provided on the other side. The clamping member 612 has a T-shaped groove 6121 on one side that slides with the T-shaped slide rail 6144, and an installation opening 6122 on the other side that corresponds to the fixing groove 6145. Thus, the clamping member 612 obtains stable guidance and anti-rollover restraint on one side through the T-shaped slide rail, while the installation opening 6122 on the other side is used to accommodate components such as the pawl 621 in the anti-rollover assembly 62, achieving the integration of the clamping and anti-rollover structures.

[0028] like Figure 7-13 As shown, the anti-reverse assembly 62 includes a pawl 621, a ratchet slider 622, an operating pin 623, and a fastening pin 624. The pawl 621 includes a pawl 6211 and an elastic plate 6212. The pawl 6211 is rotatably mounted in the mounting opening 6122 of the clamping member 612. The elastic plate 6212 abuts against the upper surface of the pawl 6211, giving the pawl 6211 a preload force in the direction of the ratchet, thereby enabling the pawl 6211 to reliably engage with the ratchet in the clamped state.

[0029] The ratchet slider 622 is slidably disposed within the fixed groove 6145. A ratchet 6221 is provided on one side of the ratchet slider 622, and a pawl 6211 engages unidirectionally with the ratchet 6221 to limit the reverse return of the clamping member 612. A movable groove 6146 is provided on the support 614, and an operating pin 623 is located on one side of the ratchet slider 622 and passes through the movable groove 6146, allowing the ratchet slider 622 to slide along the extension direction of the movable groove 6146 to switch between the engaged and disengaged positions. A pin hole 6147 is provided on the support 614, and a fastening pin 624 is disposed in the pin hole 6147 and connected to the ratchet slider 622 to position and fix the ratchet slider 622 in the working position, preventing the ratchet slider 622 from shaking due to transportation vibration and affecting the reliability of the anti-reverse mechanism.

[0030] In one embodiment, the ratchet 6221 includes a plurality of ratchet teeth 62211 spaced apart along the sliding direction of the clamping member 612. The ratchet teeth 62211 are provided with a one-way inclined surface to cooperate with the pawl 6211 to form a one-way anti-retraction, so that the pawl 6211 can pass over the teeth in the clamping direction and abut against the anti-retraction in the return direction.

[0031] like Figure 1 , Figure 10 , Figure 14As shown, the support platform 3 includes a first support platform 31 and a second support platform 32. The second support platform 32 is located at the top of the lifting mechanism 4 and is lifted vertically under the drive of the lifting mechanism 4. In this embodiment, to adapt to different shapes and clamping position requirements, at least one guide groove 33 extending laterally along the frame is provided on both the first support platform 31 and the second support platform 32, and several positioning holes 34 are arranged parallel to the guide groove 33. The base 613 is provided with a guide rail 6131 that slides with the guide groove 33. The base 613 has fixing holes 6132 coaxial with the positioning holes 34 at both ends. By fasteners passing through the fixing holes 6132 and cooperating with the positioning holes 34, the clamping mechanism 6 can be adjusted and quickly positioned and fixed in the lateral position, thereby adapting to different equipment shapes and clamping position requirements.

[0032] Working Principle: When using the multi-compartment substation equipment conveying device of the present invention, the guide assembly 5 is first aligned with the prefabricated compartment ground guide groove and the pusher frame 1 is pushed. The guide wheel 522 cooperates with the guide groove to constrain the travel path. The lifting or lowering state of the guide wheel 522 is switched by a linkage mechanism composed of L-shaped rod 533, connecting rod 534, first connecting rod 531, second connecting rod 532 and guide block 521. The movable part 535 at the free end of L-shaped rod 533 reciprocates in the fan-shaped guide groove 12 through follower pin 53522, and forms a limit and hold at the slot 13, so that the guide wheel 522 has a clear limit stroke and state stability in the lifting and lowering positions.

[0033] When the device is placed above the clamping assembly 61 and slowly lowered, the lower part of the device abuts against the clamping member 612. The device's own weight causes the clamping member 612 to slide along the guide direction of the rectangular groove 6143. The clamping member 612 drives the left and right clamping members 611 to rotate in opposite directions through the connecting ear plate 616 and the connecting rod 615, so that the arc-shaped clamping arm 6112 clamps and limits the device. During the clamping process, the anti-reverse assembly 62, under the pre-tightening action of the elastic plate 6212, keeps the pawl 6211 and the ratchet 6221 in unidirectional engagement, and is positioned and retained by the fastening pin 624, limiting the reverse return of the clamping member 612, thereby preventing the clamping from loosening due to transportation vibration or reverse impact. When the device needs to be released, pull out the fastening pin 624 and push the operating column 623 to switch the ratchet slider 622 to the disengaged position along the moving groove 6146, thereby releasing the anti-reverse engagement between the pawl 6211 and the ratchet 6221, realizing the return of the clamping part 612 and the opening of the clamping part 611, thus completing the unlocking and unloading.

[0034] In addition, by using the guide groove 33 and positioning hole 34 of the support platform 3 in conjunction with the guide rail 6131 and fixing hole 6132 of the base 613, the clamping mechanism 6 can be adjusted and quickly positioned laterally along the frame 1, thereby improving its adaptability to equipment of different shapes and sizes.

[0035] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
