Description

Technical Field

[0001] This utility model relates to the field of gate technology for water conservancy projects, and in particular to a roller structure for a hydropower station gate and a hydropower station gate device. Background Technology

[0002] Existing technologies, such as the multi-roller gate eccentric shaft device and the gate equipped with it disclosed in patent publication number CN223329783U, use eccentric shafts for installation between rollers and gates, and the gate is a rolling gate. Each eccentric shaft is connected to its corresponding roller. The eccentric shaft passes through a pre-reserved shaft hole on the gate through the main shaft body, with both ends exposed. One end forms an eccentric shaft section that extends outward from the gate, and the other end has an external thread and is detachably locked to the gate by a locking nut and a washer. The eccentric shaft section is eccentrically set relative to the main shaft body and parallel to the central axis. Rollers are coaxially mounted on the eccentric shaft section, and the outer circumference of the rollers rolls in contact with the gate groove track. The distance between the rollers and the gate groove track in the horizontal direction opposite to the gate groove track is adjustable by the eccentric shaft.

[0003] The existing technology has the following problems:

[0004] In existing technologies, the gate rollers make rolling contact with the gate track, resulting in rapid wear, short service life, heavy weight, and high cost.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0006] In view of the above problems, this application provides a roller structure and a gate device for hydropower stations, which solves the technical problems of the existing gate rollers rolling contacting the gate track, resulting in rapid wear, short service life, heavy weight, and high cost.

[0007] To achieve the above objectives, in a first aspect, this application provides a roller structure for a hydropower station gate, comprising:

[0008] The roller body has an outer circumference for rolling contact with the gate groove track. A wear-resistant layer is provided on the outer circumference, and the thickness of the wear-resistant layer is greater than a preset value.

[0009] The roller body is provided with a mounting hole for mounting a copper sleeve. A threaded hole is provided on the outer side of the mounting hole. The roller body is provided with two or more grooves arranged around the center of the roller body. The grooves are provided with weight-reducing holes that penetrate the roller body.

[0010] Unlike existing technologies, the technical solution of this application involves providing a wear-resistant layer around the outer circumference of the roller body. The thickness of the wear-resistant layer is greater than a preset value. The wear-resistant layer of the roller body is made by surface hardening and has a depth of more than 20mm. Then, the outer circumference of the roller body is machined to ensure the flatness of the outer circumference and improve the service life of the gate roller. Furthermore, by providing two or more grooves on the roller body, with the grooves arranged around the center of the roller body and weight-reduction holes penetrating the roller body, the weight of the gate roller can be effectively reduced, saving materials and reducing costs.

[0011] In one embodiment of this utility model, the thickness of the wear-resistant layer is greater than 20mm.

[0012] Thus, the thickness of the wear-resistant layer is greater than 20mm, ensuring that the wear-resistant layer is between 20mm and 30mm, thereby increasing the thickness of the wear-resistant layer and extending the service life of the gate roller.

[0013] In one embodiment of this utility model, the wear-resistant layer is integrally formed with the roller body.

[0014] This makes it easier to manufacture gate rollers.

[0015] In one embodiment of this utility model, two or more grooves are provided on both the left and right sides of the roller body, and a reinforcing beam is provided between two adjacent grooves.

[0016] Thus, two or more grooves are provided on both the left and right sides of the roller body, and a reinforcing beam is provided between two adjacent grooves, which saves materials and reduces costs while ensuring the integrity of the roller body.

[0017] In one embodiment of this utility model, a protrusion is provided on one side of the roller body, and the threaded hole is provided on the protrusion.

[0018] Thus, the threaded hole is used to fix the cover plate, which is set at one end of the eccentric shaft, and the roller can be rotatably mounted on the eccentric shaft through the copper sleeve.

[0019] To achieve the above objectives, in a second aspect, this application also provides a hydropower station gate device, including a roller structure for a hydropower station gate as described in any of the above claims, a gate slot seat, a gate slot track, an eccentric shaft, and a gate body;

[0020] The roller structure is disposed within the gate slot seat, the gate slot seat is provided with an installation groove, the gate slot track is disposed within the installation groove, the roller structure contacts the gate slot track, and the roller structure is rotatably connected to the gate body via an eccentric shaft.

[0021] Unlike existing technologies, the technical solution of this application features a wear-resistant layer on the outer circumference of the roller body. The thickness of the wear-resistant layer is greater than a preset value. The outer circumference of the roller body contacts the gate track, and the surfaces of the outer circumference of the roller body and the gate track are in contact. The wear-resistant layer on the outer circumference of the roller body is harder than the surface of the gate track. This combination of hardness and softness reduces mutual wear and improves the service life of the gate roller. The weight-reducing holes effectively reduce the weight of the gate roller, saving materials and reducing costs. The eccentric shaft ensures that the gate roller and the gate track maintain good and stable rolling contact.

[0022] In one embodiment of this utility model, a gate slot seat is provided at both the left and right ends of the gate body, and there are two or more roller structures at both the left and right ends of the gate body.

[0023] Thus, the gate body has two or more roller structures at both ends, and the gate body can contact the gate groove track through two or more rollers, thereby improving the stability of the gate body when moving up and down.

[0024] In one embodiment of this utility model, a door groove track is correspondingly provided on the door groove seat, and both door groove tracks are located at the downstream end of the gate body. The cross-sectional shape of the door groove track is I-shaped, and the door groove track is integrally formed.

[0025] Thus, both gate slot tracks are located at the downstream end of the gate body. Due to the impact of upstream water pressure, the gate rollers move downstream, causing them to contact the gate slot tracks. The cross-sectional shape of the gate slot tracks is I-shaped, which improves the stability of the gate slot tracks. The gate slot tracks are integrally formed, reducing the number of connecting parts and improving flatness.

[0026] As one embodiment of the present invention, the hydropower station gate device further includes a limiting member, which is disposed between the gate body and the gate slot seat and is fixed on the gate body. A limiting member is provided at both the left and right ends of the gate body.

[0027] Thus, the limiting component is used to limit the distance between the gate body and the gate slot seat. The gate roller is fixed on the gate body, and the gate slot track is fixed on the gate slot seat. The limiting component ultimately limits the distance between the gate roller and the gate slot track, so as to avoid the gate roller having too large a contact area with the gate slot track, which would make it difficult for the gate roller to rotate and wear out too quickly.

[0028] In one embodiment of this utility model, the hydropower station gate device further includes a guide assembly. The limiting member is disposed at the downstream end of the gate body and is located inside the gate slot seat. The guide assembly is disposed at the upstream end of the gate body and is located outside the gate slot seat. The guide assembly includes a mounting base and a guide wheel. The guide wheel is mounted on the upstream end of the gate body through the mounting base and contacts the outer wall of the gate slot seat.

[0029] Thus, a guide assembly is provided at both the left and right ends of the gate body. The guide assembly is located at the upstream end of the gate body. The guide assembly includes a mounting base and a guide wheel. The guide wheel is mounted on the upstream end of the gate body through the mounting base. The guide wheel contacts the outer wall of the gate slot seat. The two guide wheels guide the gate body and restrict the left and right position of the gate body.

[0030] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0056] In existing technologies, the gate rollers make rolling contact with the gate track, resulting in rapid wear, short service life, heavy weight, and high cost.

[0057] In view of this, the present application provides a roller structure and a gate device for a hydropower station, including a roller body 1. The outer circumference of the roller body 1 is used for rolling contact with the gate groove track 3 of the gate. A wear-resistant layer 11 is provided on the outer circumference, and the thickness of the wear-resistant layer 11 is greater than a preset value. The roller body 1 is provided with a mounting hole 12 for installing a copper sleeve. A threaded hole 13 is provided on the outer side of the mounting hole 12. The roller body 1 is provided with two or more grooves 14, which are arranged around the center of the roller body 1. The grooves 14 are provided with weight-reducing holes 15, which penetrate the roller body 1. Thus, by providing a wear-resistant layer 11 around the outer circumference of the roller body 1, the thickness of the wear-resistant layer 11 is greater than a preset value. The wear-resistant layer 11 of the roller body 1 is made by surface hardening and has a depth of more than 20mm. Then, the outer circumference of the roller body 1 is machined to ensure the flatness of the outer circumference and improve the service life of the gate roller. The groove 14 is provided with a weight-reducing hole 15, which penetrates the roller body 1, and can effectively reduce the weight of the gate roller, save materials, and reduce costs.

[0058] According to some embodiments of this application, please refer to Figures 1 to 6 This embodiment relates to a roller structure for a hydropower station gate, including a roller body 1. The outer circumference of the roller body 1 is used for rolling contact with the gate groove track 3 of the gate. A wear-resistant layer 11 is provided on the outer circumference, and the thickness of the wear-resistant layer 11 is greater than a preset value. The roller body 1 is provided with a mounting hole 12 for installing a copper sleeve. A threaded hole 13 is provided on the outer side of the mounting hole 12. The roller body 1 is provided with two or more grooves 14, which are arranged around the center of the roller body 1. The grooves 14 are provided with weight-reducing holes 15, which penetrate the roller body 1.

[0059] The roller body 1 is integrally formed by casting. The outer circumference of the roller body 1 undergoes surface heat treatment to form a wear-resistant layer 11. The thickness of the wear-resistant layer 11 on the outer circumference of the roller body 1 is ( Figure 6 To achieve the preset thickness (the size of the number d), the surface hardness of the outer circumference of the roller body 1 is increased, and then the surface of the outer circumference of the roller body 1 is machined to improve the surface smoothness of the outer circumference of the roller body 1.

[0060] In this embodiment, a wear-resistant layer 11 is provided on the outer circumference of the roller body 1. The thickness of the wear-resistant layer 11 is greater than a preset value. The wear-resistant layer 11 of the roller body 1 is made by surface hardening and has a depth of more than 20mm. Then, the outer circumference of the roller body 1 is machined to ensure the flatness of the outer circumference and improve the service life of the gate roller. Two or more grooves 14 are provided on the roller body 1. The two or more grooves 14 are arranged around the center of the roller body 1. The grooves 14 are provided with weight-reducing holes 15, which penetrate the roller body 1. This can effectively reduce the weight of the gate roller, save materials, and reduce costs.

[0061] According to some embodiments of this application, optionally, the thickness of the wear-resistant layer 11 is greater than 20 mm.

[0062] Thus, the thickness of the wear-resistant layer 11 is greater than 20mm, ensuring that the wear-resistant layer 11 is between 20mm and 30mm, thereby increasing the thickness of the wear-resistant layer 11 and improving the service life of the gate roller.

[0063] According to some embodiments of this application, optionally, the wear-resistant layer 11 is integrally formed with the roller body 1.

[0064] This makes it easier to manufacture gate rollers.

[0065] According to some embodiments of this application, optionally, two or more grooves 14 are provided on both the left and right sides of the roller body 1, and a reinforcing beam 16 is provided between two adjacent grooves 14.

[0066] The groove 14 and the weight reduction hole 15 can both reduce the weight of the roller body 1, saving materials.

[0067] Thus, two or more grooves 14 are provided on both the left and right sides of the roller body 1, and a reinforcing beam 16 is provided between two adjacent grooves 14, which saves materials and reduces costs while ensuring the roller body 1.

[0068] According to some embodiments of this application, optionally, a protrusion 17 is provided on one side of the roller body 1, and a threaded hole 13 is provided on the protrusion 17.

[0069] The cover plate covers the protrusion 17 on one side of the roller body 1. The threaded hole 13 is used to fix the cover plate, and the mounting hole 12 is used to install the copper sleeve. The copper sleeve is used to install the eccentric shaft.

[0070] Thus, the threaded hole 13 is used to fix the cover plate, which is set at one end of the eccentric shaft 4, and the roller can be rotatably set on the eccentric shaft 4 through the copper sleeve.

[0071] This embodiment also relates to a gate device for a hydropower station, such as... Figure 1 and Figure 2As shown, the gate includes a roller structure for a hydropower station gate, a gate slot seat 2, a gate slot track 3, an eccentric shaft 4, and a gate body 5, as described above. The roller structure is installed in the gate slot seat 2, the gate slot seat 2 is provided with an installation slot, the gate slot track 3 is installed in the installation slot, the roller structure is in contact with the gate slot track 3, and the roller structure is rotatably connected to the gate body 5 through the eccentric shaft 4.

[0072] In this embodiment, the eccentric shaft of the roller body 1 is installed on the gate body 5. The eccentric shaft is installed on the gate body 5 by two mounting plates. As in the prior art patent publication number CN223329783U, a pair of mounting plates with pre-reserved shaft holes are arranged on the gate according to the installation position of each eccentric shaft. The shaft holes of the pair of mounting plates are aligned along the axial direction of the main shaft. The main shaft passes through the two shaft holes and is mounted on the pair of mounting plates. The exposed end on one side inside the gate is detachably fastened to the mounting plate by the locking nut and washer.

[0073] In this embodiment, a wear-resistant layer 11 is provided on the outer circumference of the roller body 1. The thickness of the wear-resistant layer 11 is greater than a preset value. The outer circumference of the roller body 1 contacts the gate track 3, and the outer circumference of the roller body 1 and the surface of the gate track 3 are in contact. The wear-resistant layer 11 on the outer circumference of the roller body 1 is harder than the surface of the gate track 3. One is hard and the other is soft, which reduces mutual wear and improves the service life of the gate roller. The weight-reducing hole 15 can effectively reduce the weight of the gate roller, save materials, and reduce costs. The eccentric shaft 4 can keep the gate roller and the gate track 3 in good and stable rolling contact.

[0074] According to some embodiments of this application, optionally, a gate slot seat 2 is provided at both the left and right ends of the gate body 5, and there are two or more roller structures at the left and right ends of the gate body 5.

[0075] Thus, the gate body 5 has two or more roller structures at its left and right ends, and the left and right ends of the gate body 5 can contact the gate groove track 3 through two or more rollers, thereby improving the stability of the gate body 5 in raising and lowering.

[0076] According to some embodiments of this application, optionally, a door groove track 3 is provided on the door groove seat 2, and both door groove tracks 3 are provided at the downstream end of the gate body 5. The cross-sectional shape of the door groove track 3 is I-shaped, and the door groove track 3 is integrally formed.

[0077] Thus, both gate track 3 are located at the downstream end of the gate body 5. According to the impact of the upstream water pressure, the gate roller moves downstream, so that the gate roller contacts the gate track 3. The cross-sectional shape of the gate track 3 is I-shaped, which improves the stability of the gate track 3. The gate track 3 is integrally formed, reducing the number of connecting parts of the gate track 3. There is no need to connect the two gate tracks 3 together, which improves the overall flatness of the gate track 3.

[0078] According to some embodiments of this application, optionally, the hydropower station gate device further includes a limiting member 6, which is disposed between the gate body 5 and the gate slot seat 2. The limiting member 6 is fixed on the gate body 5, and a limiting member 6 is provided at both the left and right ends of the gate body 5.

[0079] The limiting member 6 is fixed to the downstream end of the gate body 5 by bolts. The limiting member 6 has a certain elasticity. When the gate body 5 squeezes the limiting member 6, the limiting member 6 provides a restoring force to the gate body 5, ensuring the distance between the gate roller and the gate groove track 3.

[0080] Thus, the limiting component 6 is used to limit the distance between the gate body 5 and the gate slot seat 2. The gate roller is fixed on the gate body 5, and the gate slot track 3 is fixed on the gate slot seat 2. The limiting component 6 ultimately limits the distance between the gate roller and the gate slot track 3, so as to avoid the gate roller having too large a contact area with the gate slot track 3, which would make it difficult for the gate roller to rotate and wear out too quickly.

[0081] According to some embodiments of this application, optionally, the hydropower station gate device further includes a guide assembly. The limiting member 6 is disposed at the downstream end of the gate body 5 and is located inside the gate slot seat 2. The guide assembly is disposed at the upstream end of the gate body 5 and is located outside the gate slot seat 2. The guide assembly includes a mounting base 71 and a guide wheel 72. The guide wheel 72 is mounted on the upstream end of the gate body 5 through the mounting base 71 and contacts the outer wall of the gate slot seat 2.

[0082] The guide wheel 72 is fixed at the upstream end of the gate body 5, and a fixing plate 21 is provided at the upstream end of the gate slot seat 2. The fixing plate 21 has an L-shaped cross section and is in contact with the guide wheel 72.

[0083] Thus, a guide component is provided at both the left and right ends of the gate body 5. The guide component is set at the upstream end of the gate body 5. The guide component includes a mounting base 71 and a guide wheel 72. The guide wheel 72 is installed at the upstream end of the gate body 5 through the mounting base 71. The guide wheel 72 contacts the outer wall of the gate slot seat 2. The two guide wheels 72 play a guiding role for the gate body 5 and limit the left and right position of the gate body 5.
