Description

Technical Field

[0001] The invention relates to the field of water conservancy and hydropower engineering, and in particular to an elastic supporting device. Background Art

[0002] In water-related projects such as water conservancy, hydropower, water environment, municipal water supply and drainage, the side and reverse supports of gates and trash racks mainly include simply supported wheel devices, slider reverse support devices, elastic reverse wheel devices, elastic slider devices, etc. The main support bears the water retaining pressure, and the side and reverse supports mainly play a guiding and limiting role.

[0003] During the application of the simply supported wheel device and the slider reverse support device, a gap needs to be reserved between the device and the supporting embedded parts, which results in the device being unable to provide pre-pressure and poor guiding effect. When it is applied to a gate, it is easy to cause the gate to leak, and when it is applied to a trash rack, it is easy to cause vibration damage to the trash rack.

[0004] The above problems can be solved to a certain extent by using elastic anti-wheel devices and elastic slider devices, which can provide elastic support and thus provide pre-pressure for the gate or trash rack. However, both devices provide deformation support through rubber blocks, and the ultimate bearing capacity of rubber blocks is relatively small. If the gate or trash rack is greatly deformed due to the water hammer and the reverse impact force, the reverse support device will be destroyed. Summary of the invention

[0005] The object of the present invention is to provide an elastic supporting device, which can solve the problem in the prior art that the reverse supporting device is easily damaged when subjected to a large reverse impact force.

[0006] The present invention is achieved in that:

[0007] 4. The repairing kit for automotive dents, according to claim 1, wherein the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a spring, wherein the bosses comprise a through-hole, a screw bolt, and a spring. The through-hole comprises a through-hole, and the two foot pieces comprise a screw bolt, a screw bolt, and a spring.

[0008] In a feasible implementation manner, the elastic member is detachably installed between the base and the slider.

[0009] In a feasible implementation scheme, the elastic support device also includes a limiter, which is used to limit the maximum distance between the slider and the base; a limiter hole is provided on the slider, and the limiter includes a connected rod and a head, the rod is connected to the base after passing through the limiter hole, and the head is located on the side of the limiter hole away from the base, and the diameter of the head is larger than the aperture of the limiter hole.

[0010] In a feasible embodiment, the adjusting member is an adjusting bolt, the end support structure is provided with a positioning hole, the base plate is provided with a first threaded hole, the adjusting bolt passes through the positioning hole and is screwed into the first threaded hole, and the installation position of the base plate is adjusted by adjusting the length of the adjusting bolt screwed into the base plate.

[0011] In a feasible implementation, the end support structure is provided with two limiting grooves, and the two ends of the sliding block extend into the corresponding limiting grooves respectively.

[0012] In a feasible embodiment, the end support structure is provided with a recessed groove, the depth of which is greater than the axial length of the head of the adjusting bolt along the adjusting bolt, and the head of the adjusting bolt is located in the recessed groove.

[0013] In a feasible implementation manner, the mounting plate is provided with mounting holes.

[0014] In a feasible implementation scheme, the slider is provided with a first limit column, the bottom plate is provided with a second limit column, the two ends of the pressure spring are respectively mounted on the first limit column and the second limit column, and the sum of the axial length of the first limit column and the axial length of the second limit column is less than or equal to the depth of the accommodating cavity.

[0015] The beneficial effects of the present invention include at least:

[0016] The elastic support device provided by the present invention includes a base, a slider and an elastic member. A receiving cavity is provided in the base. The elastic member is located between the base and the slider, and one end of the elastic member extends into the receiving cavity and is compressed between the base and the slider. The above-mentioned elastic support device can be installed on equipment such as gates or trash racks. Taking the installation of the elastic support device on the gate as an example, the base of the elastic support device is connected to the gate, the slider is located on the side away from the gate, the initial support size is larger than the corresponding gate slot size, and when the gate enters the gate slot, the slider contacts the supporting embedded part, and the elastic member is further compressed. The total compression of the elastic member corresponds to the designed preload. When subjected to external force, the slider can move relative to the base and compress the elastic member so that the elastic member extends into a larger area of ​​the receiving cavity or even completely extends into the receiving cavity. After the external force is reduced or disappears, the elastic member pushes the slider to move in the opposite direction under the elastic action to provide a certain preload for the gate. Such a configuration enables the slider to move within a certain elastic range relative to the base and always contact the supporting embedded part. That is to say, on the one hand, the elastic support device can provide a certain pre-pressure for the gate; on the other hand, when the gate is subjected to a large impact, the slider compresses the elastic member and completely presses the elastic member into the accommodating cavity to protect the elastic member and avoid large deformation of the elastic member to a certain extent. Since the base can limit the movement range of the slider along the compression direction of the elastic member, the compression amount of the slider on the elastic member is within the set range, that is, it has a protective effect on the elastic member. When the slider moves to the maximum position along the compression direction of the elastic member, the base prevents the slider from continuing to compress the elastic member. At this time, the elastic support device as a whole forms a rigid support, which can withstand a large load, resist a greater impact force, and is not easily damaged.

[0017] Furthermore, the base includes a bottom plate, and the elastic member is located between the slider and the bottom plate, and the position of the bottom plate is adjustable. When the gate slot size deviates, adjusting the position of the bottom plate can ensure that the total compression of the elastic member remains unchanged, thereby providing a stable pre-pressure. The compression of the elastic anti-wheel device and the elastic slider device in the prior art cannot be adjusted. Due to the objective manufacturing and installation errors, it is difficult to accurately provide the pre-pressure required by the design, and the problem of the gate being prone to water leakage and the trash rack being prone to vibration cannot be completely solved. However, since the position of the bottom plate in the present application is adjustable, the compression of the elastic member is adjustable, thereby being able to accurately provide the pre-pressure required by the design, thereby solving the problem of the gate being prone to water leakage and the trash rack being prone to vibration.

[0018] In summary, compared with the elastic device in the prior art, the present application can provide precise pre-pressure for equipment such as gates or trash racks, and at the same time, can withstand a larger load and is not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] First embodiment

[0049] Please refer to Figure 1-Figure 7 As shown, this embodiment provides an elastic support device, which includes: a base 100, a slider 200 and an elastic member 300, the base 100 has a receiving cavity, one end of the elastic member 300 extends into the receiving cavity, and the elastic member 300 is located between the base 100 and the slider 200; the slider 200 can move relative to the base 100 to compress the elastic member 300, and the base 100 can limit the movement range of the slider 200 along the compression direction of the elastic member 300.

[0050] Specifically, in a specific embodiment, the base 100 has a limiting surface, and when the elastic support device is in the initial position (not subject to external force), under the action of the elastic member 300, there is a set distance between the slider 200 and the limiting surface of the base 100, and the set distance is the maximum moving distance of the slider 200 along the compression direction of the elastic member 300. When the slider 200 contacts the limiting surface, the limiting surface prevents the slider 200 from continuing to compress the elastic member 300, thereby protecting the elastic member 300.

[0051] In a specific embodiment, the slider 200 is installed outside the accommodating cavity, the limiting surface belongs to the end surface of the base 100, and the limiting surface is located outside the opening of the accommodating cavity. After being subjected to a large external force, the slider 200 can compress the elastic member 300 and finally abut against the limiting surface. At this time, the slider 200 forms a rigid connection with the base 100.

[0052] The elastic support device can be applied to equipment such as gates or trash racks as a reverse support to play a supporting limit role. In specific applications, different supporting reaction forces can be provided by selecting elastic members 300 with different stiffness.

[0053] In order to facilitate replacement of the elastic member 300, in a feasible implementation, the elastic member 300 is detachably installed between the base 100 and the slider 200. With such an arrangement, on the one hand, different elastic members 300 can be replaced according to changes in demand; on the other hand, after long-term use, the elastic support device can be extended in service life by replacing a new elastic member 300.

[0054] The elastic support device also includes a limit member 400, which is used to limit the maximum distance between the slider 200 and the base 100; a limit hole 220 is set on the slider 200, and the limit member 400 includes a connected rod and a head, the rod passes through the limit hole 220 and is connected to the base 100, and the head is located on the side of the limit hole 220 away from the base 100, and the diameter of the head is larger than the aperture of the limit hole 220.

[0055] Specifically, the axial direction of the rod of the limiting member 400 is the same as the moving direction of the slider 200. The limiting member 400 is coaxial with the limiting hole 220, and the diameter of the rod of the limiting member 400 is close to the aperture of the limiting hole 220, so that the limiting member 400 not only plays a limiting role for the slider 200, but also plays a guiding role. In the process of the slider 200 moving relative to the base 100, the slider 200 moves along the axial direction of the rod of the limiting member 400, and the rod of the limiting member 400 plays a guiding role for the slider 200. After the slider 200 moves a certain distance, the outer side surface of the slider 200 facing away from the base 100 abuts against the head of the limiting member 400, and the limiting member 400 plays a limiting role for the slider 200, preventing the slider 200 from continuing to move away from the base 100.

[0056] Preferably, if Figure 4 and Fig.11 As shown, the stopper 400 is threadedly connected to the base 100, an external thread is provided on the rod of the stopper 400, and a second threaded hole 124 is provided on the base 100, the second threaded hole 124 is opposite to the stopper hole 220, and the rod of the stopper 400 passes through the stopper hole 220 and is screwed into the second threaded hole 124, thereby being connected to the base 100. By changing the length of the portion of the rod of the stopper 400 screwed into the second threaded hole 124, the maximum distance between the slider 200 and the base 100 can be adjusted to adapt to the manufacturing and installation accuracy error of the embedded parts.

[0057] like Figure 4 , Figure 7-10 As shown, a countersunk hole 230 is provided on the side of the slider 200 away from the base 100. The countersunk hole 230 is connected to the limiting hole 220, and the aperture of the countersunk hole 230 is larger than the aperture of the limiting hole 220. The countersunk hole 230 is used to place the head of the limiting member 400 to prevent the head of the limiting member 400 from protruding from the side of the slider 200 away from the base 100. Figure 7 As shown in the figure, when the elastic support device is placed horizontally and the slider 200 is located at the top, the top surface of the slider 200 is located at the top of the elastic support device, and the head of the stopper 400 extends into the countersunk hole 230, and the head of the stopper 400 does not exceed the top surface of the slider 200. In this way, the slider 200 is in contact with the embedded part. Figure 7 and Fig.10 As shown, the side surface of the slider 200 away from the base 100 is a curved surface, preferably a smooth curved surface.

[0058] In an optional implementation, the limiting member 400 may directly adopt a limiting bolt, and the rod portion thereof is provided with threads along the axial direction.

[0059] Alternatively, in another feasible implementation, only a part of the rod of the stopper 400 is provided with threads. Specifically, one end of the rod is connected to the head, and the other end is provided with threads for connecting to the base 100, and a part of the rod near the head may not be provided with threads.

[0060] like Figure 2 , Figure 6 , Figure 11-Figure 15As shown, the base 100 includes an assembly plate 110, an end support structure 120 and a bottom plate 130. The assembly plate 110 is provided with a through hole 131. The end support structure 120 is an annular structure and is installed on one side of the assembly plate 110. The bottom plate 130 is fixed in the through hole 131 by an adjusting member, and a receiving cavity is formed between the bottom plate 130 and the end support structure 120. The adjusting member is used to adjust the axial installation position of the bottom plate 130 in the through hole 131 to change the depth of the receiving cavity. When the elastic member 300 remains unchanged, the depth of the receiving cavity is changed, that is, the compression length of the elastic member 300 is changed, so as to accurately control the supporting reaction force of the elastic supporting device.

[0061] Preferably, the adjusting member is an adjusting bolt 500, the end support structure 120 is provided with a positioning hole 123, the bottom plate 130 is provided with a first threaded hole 132, the adjusting bolt 500 passes through the positioning hole 123 and is screwed into the first threaded hole 132, and the installation position of the bottom plate 130 is adjusted by adjusting the length of the adjusting bolt 500 screwed into the bottom plate 130. Figure 6 As shown, the adjusting bolt 500 extends into the positioning hole 123 through one side of the end support structure 120, and is then screwed into the first threaded hole 132. The longer the adjusting bolt 500 is screwed into the first threaded hole 132, the smaller the distance between the base plate 130 and the end support structure 120, and the smaller the depth of the accommodating cavity, thereby making the compression length of the elastic member 300 larger.

[0062] In a feasible implementation, the end support structure 120 is provided with two limiting grooves, and the two ends of the slider 200 extend into the corresponding limiting grooves respectively, and the limiting surface of the base 100 is the bottom surface of the limiting groove. During the movement of the slider 200, at least a part of the slider 200 is located in the limiting groove, and the two ends of the slider 200 are respectively limited by their corresponding limiting grooves.

[0063] In a feasible embodiment, the end support structure 120 is provided with a recessed groove, the depth of which is greater than the axial length of the head of the adjusting bolt 500 along the adjusting bolt 500 , and the head of the adjusting bolt 500 is located in the recessed groove.

[0064] like Fig.11As shown, the plate surface of the assembly plate 110 is rectangular, and the end support structure 120 is a rectangular annular structure. For example, the end support structure 120 includes two first support plates 121 and two second support plates 122. The length direction of the two first support plates 121 is the same as the length direction of the assembly plate 110, and the length direction of the two second support plates 122 is the same as the width direction of the assembly plate 110. If the axial direction of the through hole 131 of the assembly plate 110 is taken as a reference, the length of the first support plate 121 is greater than the length of the second support plate 122. In other words, when the assembly plate 110 is placed in a horizontal direction and the end support structure 120 is located above the assembly plate 110, the height of the first support plate 121 is greater than the height of the second support plate 122. Since there is a height difference between the first support plate 121 and the second support plate 122, a concave structure is formed between the first support plate 121 and the second support plate 122, and the concave structure is a limiting groove for limiting the end of the slider 200.

[0065] like Fig.11 and Fig.12 As shown, further, the sink is disposed on the side of the first support plate 121 away from the assembly plate 110. The positioning hole 123 passes through the first support plate 121, and one end of the positioning hole 123 is located in the sink, and the other end of the positioning hole 123 is opposite to the through hole 131.

[0066] In a feasible embodiment, a mounting hole 111 is provided on the mounting plate 110. The mounting hole 111 is reserved on the mounting plate 110 to facilitate fixing the mounting plate 110 to a gate or a trash rack.

[0067] In a feasible implementation of this embodiment, the elastic member 300 is a pressure spring. The two ends of the pressure spring can be respectively connected to the base 100 (specifically the bottom plate 130) and the slider 200 by snapping or hooking. Alternatively, in a preferred implementation, as Figure 4 , Figure 8 , Fig.10 and Fig.15 As shown, the slider 200 is provided with a first limiting column 210, the bottom plate 130 is provided with a second limiting column 140, the two ends of the pressure spring are respectively sleeved on the first limiting column 210 and the second limiting column 140, and the sum of the axial length of the first limiting column 210 and the axial length of the second limiting column 140 is less than or equal to the depth of the accommodating cavity.

[0068] The first limiting column 210 limits one end of the pressure spring and makes the position between this end of the pressure spring and the slider 200 relatively fixed; the second limiting column 140 limits the other end of the pressure spring and makes the position between the other end of the pressure spring and the base plate 130 relatively fixed.

[0069] In this embodiment, Figure 1-Figure 15 In the figure, the assembly plate 110 is a rectangular plate structure, but this shape is only one of the optional structural shapes of the assembly plate 110 and is not a limitation thereof. The plate surface of the assembly plate 110 can also be other shapes, such as circular, elliptical, oblong or polygonal. The specific shape can be selected according to the requirements of the equipment to which it is applied. Similarly, the structural shapes of the end support structure 120, the bottom plate 130 and the slider 200 are not limited to the shapes shown in the figure, but can also be other structural shapes. Figure 1-Figure 15 In the embodiment, the assembly plate 110 is a rectangular plate structure, the end support structure 120 is a rectangular ring structure, the slider 200 is a strip structure, and the bottom plate 130 is a rectangular plate structure; in another specific embodiment, when the assembly plate 110 is a rectangular plate structure, the through hole 131 on the assembly plate 110 can be circular, then the bottom plate 130 is a circular plate structure, the end support structure 120 is a circular ring structure, and the slider 200 is a circular plate structure. In other words, the shape and structure of the end support structure 120, the bottom plate 130 and the slider 200 can match the structural shape of the assembly plate 110, or can be different.

[0070] One, two or more elastic members 300 may be disposed between the slider 200 and the base 100. Figure 1-Figure 15 The elastic support device shown in the figure is a structure corresponding to installing two elastic members 300. When the number of the elastic members 300 is more, the number of the first limiting posts 210 and the second limiting posts 140 will also be set to more. Specifically, the number of the first limiting posts 210, the number of the second limiting posts 140 and the number of the elastic members 300 are the same. The multiple elastic members 300 can be arranged in a variety of forms such as distributed along a straight line, distributed along a matrix, and uniformly distributed along an annular area. Specifically, it can be set according to the number of the elastic members 300.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
