Description

Technical Field

[0001] The utility model belongs to the technical field of cable trays, and particularly relates to an installation structure for a nuclear power cable tray. Background Art

[0002] A cable tray is a rigid structure system composed of straight sections, elbows, components of trays or ladders, as well as bracket arms and hangers, etc., which has a dense support for cables. It is an important product responsible for power transmission in the low-voltage power transmission and distribution field and is widely used in buildings, industrial and mining, and factory sites. In recent years, the cable trays in the nuclear island part of nuclear power plants have started to be domesticated, but the requirements for product quality are very strict and the technical content is relatively high.

[0003] When the existing cable trays are installed, rods with fixed lengths are usually used for installation. However, the installation environment of the cable trays is variable, and the rods with fixed lengths are not conducive to adjustment according to needs during installation, and their applicability is poor. Moreover, when problems occur in the cable trays, it is necessary to climb to a high place for inspection and repair, which increases the danger of operators. Also, when it is necessary to separate the cable tray from the installation structure, it is not conducive to removing the cable tray from a high place. Therefore, an installation structure for a nuclear power cable tray is proposed. Summary of the Invention

[0004] The utility model provides an installation structure for a nuclear power cable tray, aiming to solve the problems that the rods with fixed lengths are not conducive to adjustment according to needs during installation, have poor applicability, and when problems occur in the cable trays, it is necessary to climb to a high place for inspection and repair, which increases the danger of operators, and when it is necessary to separate the cable tray from the installation structure, it is not conducive to removing the cable tray from a high place.

[0005] An embodiment of the utility model provides an installation structure for a nuclear power cable tray, including a bottom plate. A slideway is installed on the upper side of the bottom plate, and a pair of sliding sleeves are slidably connected to the slideway. Clamping bars are hinged to the tops of the sliding sleeves. Two inner cylinders are symmetrically arranged on the bottom plate, and outer cylinders are sleeved on both inner cylinders. Tops of both outer cylinders are installed with top plates. Locking bolts are installed on both sliding sleeves. A clamping and adjusting assembly is installed at the top of the inner cylinder, and a releasing assembly is installed at the bottom of the inner cylinder.

[0006] Further, a buckle is hinged to the clamping bar on the left side, and a block matching the buckle is installed on the clamping bar on the right side. The bottom wall of the inner cylinder passes through the bottom plate and is flush with the bottom wall of the bottom plate, and the bottom of the inner cylinder is fixedly connected to the bottom plate.

[0007] By adopting the above technical solution, the two clamping bars can be locked and connected by using the buckle and the block, so that the busbar can be locked to ensure stability. The bottom of the inner cylinder protruding from the bottom plate is convenient for operation at the bottom.

[0008] Further, the clamping and adjusting component includes a plurality of clamping holes formed in the outer cylinder. One end of a return spring is installed on the inner side of the top wall of the inner cylinder. The other end of the return spring is fixedly connected to a sphere. Swing bars are hinged on both sides of the sphere. A clamping bar is hinged to the end of the swing bar away from the sphere. Clamping bars are symmetrically and slidably connected to both sides of the top of the inner cylinder.

[0009] By adopting the above technical solution, with the clamping and adjusting component, when the clamping bar is squeezed, the clamping bar is separated from the clamping hole, so that the inner cylinder can move freely, and then the position between the inner cylinder and the outer cylinder can be adjusted, and further the position of the bottom plate can be changed to adjust the height of the bus duct.

[0010] Further, a through hole matching the clamping bar is formed in the inner cylinder, and the clamping bar matches the clamping hole.

[0011] By adopting the above technical solution, the through hole can be used to allow the clamping bar to slide, and then cooperate with the return spring and the sphere to move.

[0012] Further, the clamping holes are divided into two evenly distributed rows and are symmetrically distributed on the left and right sides of the outer cylinder.

[0013] By adopting the above technical solution, the clamping hole and the clamping bar can be used to cooperate to control the inner cylinder.

[0014] Further, the releasing component includes a circular hole formed in the bottom of the inner cylinder. A limiting bar is movably connected in the circular hole. A strip-shaped hole located above the circular hole is formed in the bottom of the limiting bar. The strip-shaped hole communicates with the circular hole and matches the limiting bar. Symmetrically distributed operating pieces are installed at the bottom of the limiting bar. A top pressure rod is rotatably connected to the top wall of the limiting bar. A supporting plate is sleeved on the outer side of the bottom of the top pressure rod. One end of a top pressure spring is connected to the bottom of the supporting plate. The bottom of the top pressure spring is fixedly connected to the bottom wall of the inner cylinder.

[0015] By adopting the above technical solution, the releasing component can be used to directly operate the bridge on the ground without climbing heights. The inner cylinder can slide out of the outer cylinder and descend automatically. By inserting a sheet-shaped tool into the two operating pieces and then applying an external force, the limiting bar is rotated to the position of the strip-shaped hole. At this time, under the action of the top pressure spring, the supporting plate rises and drives the top pressure rod to rise. In this way, the top pressure rod presses the sphere to move the sphere upward, which drives the clamping bar to retract from the clamping hole, enabling the inner cylinder to be released from the restriction of the clamping bar and allowing the inner cylinder to slide in the outer cylinder and descend automatically without climbing heights, reducing the danger of operation.

[0016] Further, a groove matching the sphere is formed in the top of the top pressure rod, and the elasticity of the top pressure spring is greater than that of the return spring.

[0017] By adopting the above technical solution, when the restriction is released, the top pressure spring can press the sphere to move the sphere.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The present utility model can place the bridge on the top of the slideway to support the bridge. Then slide the sliding sleeve, so that the sliding sleeve drives the two clamping strips to approach, and then through the connection of the buckle and the clamping block, the bridge can be locked and installed. Then use the locking bolt to limit the sliding sleeve to ensure the stability of the bridge.

[0020] 2. By squeezing the two clamping strips, the clamping strips are retracted into the outer cylinder and then retracted into the inner cylinder. At this time, the inner cylinder can slide in the outer cylinder to change the overall height of the installation structure for adaptive adjustment. Then during maintenance or when disassembling the bridge from a high place, the rod body can be inserted between the two operating pieces, so that the limiting strip rotates to the position of the strip-shaped hole. At this time, under the action of the top pressure spring, the supporting plate drives the top pressure rod to rise, so that the top pressure rod presses the sphere to move upward, and the clamping strip is retracted, so that the inner cylinder can slide in the outer cylinder and automatically descend, reducing the number of climbs and the operation risk. In this way, when maintaining or separating the bridge, the bridge can be lowered to a relatively low position, which is beneficial to the operation and will not be difficult to carry due to the heavy weight of the bridge, making the operator safer.

Detailed implementation manner

[0031] In order to make the purpose, technical solution and advantages of the technical solution of the present utility model clearer, the technical solution of the embodiment of the present utility model will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present utility model. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1-7 , an installation structure for a nuclear power bridge is proposed in an embodiment of the present utility model, including a bottom plate 1, a slideway 2 is installed on the upper side of the bottom plate 1, a pair of sliding sleeves 3 are slidably connected on the slideway 2, clamping strips 5 are hinged at the tops of the sliding sleeves 3, two inner cylinders 8 are symmetrically arranged on the bottom plate 1, outer cylinders 9 are sleeved on both inner cylinders 8, top plates 10 are installed at the tops of the two outer cylinders 9, locking bolts 4 are installed on both sliding sleeves 3, the length of the locking bolt 4 exceeds the distance from the sphere 114 to the inner top wall of the inner cylinder 8, a clamping adjustment assembly is installed at the top of the inner cylinder 8, and a release assembly is installed at the bottom of the inner cylinder 8.

[0033] A buckle 6 is hinged on the clamping strip 5 on the left side, and a clamping block 7 matching the buckle 6 is installed on the clamping strip 5 on the right side. The bottom wall of the inner cylinder 8 passes through the bottom plate 1 and is flush with the bottom wall of the bottom plate 1. The bottom of the inner cylinder 8 is fixedly connected to the bottom plate 1. The two clamping strips 5 can be locked and connected by using the buckle 6 and the clamping block 7, so that the busbar can be locked to ensure stability. The bottom of the inner cylinder 8 protruding from the bottom plate 1 facilitates the operation at the bottom.

[0034] The clamping and adjusting component includes a number of clamping holes 111 formed in the outer cylinder 9. One end of a return spring 115 is installed on the inner side of the top wall of the inner cylinder 8. The other end of the return spring 115 is fixedly connected to a sphere 114. Swing bars 113 are hinged on both sides of the sphere 114. One end of the swing bar 113 away from the sphere 114 is hinged to a clamping bar 112. The clamping bars 112 are symmetrically and slidably connected to both sides of the top of the inner cylinder 8. By using the clamping and adjusting component, when the clamping bar 112 is squeezed, the clamping bar 112 can be separated from the clamping hole 111, so that the inner cylinder 8 can move freely, thereby adjusting the position between the inner cylinder 8 and the outer cylinder 9, and further changing the position of the bottom plate 1 to adjust the height of the busbar.

[0035] The inner cylinder 8 is provided with a through hole matching the clamping bar 112. The clamping bar 112 matches the clamping hole 111. The through hole allows the clamping bar 112 to slide, and further cooperates with the return spring 115 and the sphere 114 to move.

[0036] The clamping holes 111 are divided into two evenly distributed rows and are symmetrically distributed on the left and right sides of the outer cylinder 9. The cooperation between the clamping holes 111 and the clamping bars 112 can be used to control the inner cylinder 8.

[0037] The releasing component includes a circular hole 121 formed in the bottom of the inner cylinder 8. A limiting bar 122 is movably connected in the circular hole 121. A strip-shaped hole 123 located above the circular hole 121 is formed in the bottom of the limiting bar 122. The strip-shaped hole 123 is communicated with the circular hole 121 and matches the limiting bar 122. Symmetrically distributed operating pieces 124 are installed at the bottom of the limiting bar 122. A top pressure rod 127 is rotatably connected to the top wall of the limiting bar 122. A supporting plate 125 is sleeved on the outer side of the bottom of the top pressure rod 127. One end of a top pressure spring 126 is connected to the bottom of the supporting plate 125. The bottom of the top pressure spring 126 is fixedly connected to the bottom wall of the inner cylinder 8. By using the releasing component, the bridge can be operated directly on the ground without climbing heights. The inner cylinder 8 can slide out of the outer cylinder 9 and automatically descend. By inserting a sheet-shaped tool into the two operating pieces 124 and then applying an external force, the limiting bar 122 is rotated to the position of the strip-shaped hole 123. At this time, under the action of the top pressure spring 126, the supporting plate 125 rises and drives the top pressure rod 127 to rise. In this way, the top pressure rod 127 presses the sphere 114 to move the sphere 114 upward, so that the clamping bar 112 is retracted from the clamping hole 111, the inner cylinder 8 can be released from the restriction of the clamping bar 112, and the inner cylinder 8 can slide in the outer cylinder 9 and automatically descend without climbing heights, reducing the danger of operation.

[0038] The top of the top pressure rod 127 is provided with a groove matching the sphere 114. The elasticity of the top pressure spring 126 is greater than that of the return spring 115. By using the top pressure spring 126, the sphere 114 can be pressed to move the sphere 114 when the restriction is released.

[0039] The implementation manner is specifically as follows: When in use, the bridge can be placed on the top of the slideway 2 to support the bridge. Then, slide the sliding sleeve 3 so that the sliding sleeve 3 drives the two clamping strips 5 to approach. After that, through the connection between the buckle 6 and the clamping block 7, the bridge can be locked and installed. Then, use the locking bolt 4 to limit the position of the sliding sleeve 3 to ensure the stability of the bridge. Moreover, the top plate 10 can be connected to the ceiling by using the cooperation of the top plate 10 and the bolts for the subsequent erection of the bridge. And when it is necessary to adjust the height according to requirements, squeeze the two clamping strips 112. The clamping strips 112 are retracted into the outer cylinder 9 and retreat into the inner cylinder 8. At this time, the inner cylinder 8 can slide in the outer cylinder 9 to change the overall height of the installation structure for adaptive adjustment. Then, when performing maintenance or disassembling the bridge from a high place, the rod body can be inserted between the two operating pieces 124, and then an external force is applied to make the limiting strip 122 rotate to the position of the strip-shaped hole 123. At this time, under the action of the top pressure spring 126, the supporting plate 125 rises and drives the top pressure rod 127 to rise. In this way, the top pressure rod 127 presses the sphere 114 to move the sphere 114 upward, which drives the clamping strip 112 to retract from the clamping hole 111, enabling the inner cylinder 8 to be released from the restriction of the clamping strip 112, allowing the inner cylinder 8 to slide in the outer cylinder 9 and automatically descend, reducing the number of times of climbing heights and the risk of operation. In this way, when performing maintenance or separating the bridge, the bridge can be lowered to a relatively low position, which is beneficial for operation and will not be unfavorable for handling due to the heavy weight of the bridge, making the operator safer. And to ensure that the descending speed of the inner cylinder 8 is slowed down, a buffer spring can be installed between the inner cylinder 8 and the outer cylinder 9.
