Description

Technical Field

[0001] This utility model relates to the field of support height adjustment technology, specifically to a self-lifting height adjustment device for a tensile ball-shaped force measuring support and a tensile ball-shaped force measuring support. Background Technology

[0002] In certain situations, especially in coastal areas where the rock strata are thin and winds are frequent, individual bridge supports may experience tensile stress or foundation subsidence. This necessitates stringent requirements for the tensile strength and height adjustment capabilities of the supports. Currently, height adjustment devices primarily employ two methods: shim-plate adjustment and spiral adjustment. Both methods require external auxiliary jacking devices to lift the bridge beam, resulting in complex methods and procedures, cumbersome construction, and high costs. Utility Model Content

[0003] This utility model aims to provide a self-lifting height adjustment device for a tensile spherical force measuring support and a tensile spherical force measuring support, so as to solve the problems in the prior art that the height adjustment of the support requires an external auxiliary lifting device to lift the beam, the height adjustment method and process are complicated, construction is troublesome, and the cost is high.

[0004] This utility model is achieved using the following technical solution:

[0005] This utility model provides a self-lifting height adjustment device for a tensile ball-shaped force measuring support. The self-lifting height adjustment device is used to be installed between the upper support plate and the embedded plate of the tensile ball-shaped force measuring support.

[0006] The self-lifting height adjustment device includes a height adjustment base and a height adjustment slider. The height adjustment base is used to connect with the embedded plate. The top surface of the height adjustment base is provided with a groove. The groove has two inclined surfaces facing each other. A height adjustment slider is placed on each of the two inclined surfaces. The bottom surface of the height adjustment slider is an inclined surface and is adapted to the corresponding inclined surface. The height adjustment slider can slide on the corresponding inclined surface.

[0007] A telescopic component is connected between the two height adjustment sliders, which enables the two height adjustment sliders to slide synchronously along the inclined plane.

[0008] This invention directly installs a self-lifting height adjustment device between the upper support plate and the embedded plate of the tensile spherical force-measuring support. The telescopic mechanism allows two height adjustment sliders to slide synchronously on corresponding inclined surfaces, adjusting the distance between them. When the telescopic mechanism extends, the two sliders slide along the inclined surfaces, raising their height. These sliders lift the upper support plate. Simultaneously, because the upper support plate of the tensile spherical force-measuring support is connected to the base plate, the rise of the upper support plate will cause the base plate to rise as well, thus raising the support height. This self-lifting height adjustment device has a simple structure, a simple adjustment method, is easy to operate, convenient for construction, low cost, and requires no external lifting device.

[0010] The top surface of the height adjustment slider is a plane, and the top surface of the height adjustment slider is used to cooperate with the upper support plate;

[0011] The two inclined planes have the same angle of inclination.

[0012] As a preferred technical solution:

[0013] The height adjustment base is detachably connected to the embedded plate.

[0019] After adjusting the height slider to the correct position, the base of the tensile ball-shaped force measuring support separates from the embedded plate, leaving a support space. A height adjustment pad can be placed here to achieve a stable increase in the support height.

[0020] If the required height adjustment is not achieved when the two height adjustment sliders are moved away from each other to their maximum limit positions, the connection between the height adjustment base and the embedded plate should be loosened, a height adjustment pad should be placed between the height adjustment base and the embedded plate, and then the two height adjustment sliders should be adjusted to adjust the support height.

[0035] As a preferred technical solution:

[0036] A sealing ring is installed between the top surface of the wedge block and the upper support plate, and between the bottom surface of the wedge block and the inclined surface.

[0037] This utility model further provides a tensile spherical force measuring support without external auxiliary height adjustment, including an upper support plate, a spherical crown liner, an intermediate steel plate, a bottom basin, and a pre-embedded plate arranged from top to bottom;

[0051] 1. This utility model directly installs a self-lifting height adjustment device between the upper support plate and the embedded plate of the tensile spherical force-measuring support. The extension and retraction of the telescopic component allows two height adjustment sliders to slide synchronously on corresponding inclined surfaces, adjusting the distance between them. When the telescopic component extends, the two height adjustment sliders slide along the corresponding inclined surfaces, thus raising their height. The height adjustment sliders lift the upper support plate. Simultaneously, because the upper support plate of the tensile spherical force-measuring support is connected to the base plate, the rise of the upper support plate will drive the base plate to rise together, achieving the goal of raising the support height. This utility model's self-lifting height adjustment device has a simple structure, a simple height adjustment method, is easy to operate, convenient for construction, low cost, and requires no external lifting device.

[0052] 2. After the height adjustment sliders are adjusted to their positions, the base of the tensile ball-shaped force measuring support separates from the embedded plate, leaving a support space. Height adjustment shims can be placed here to achieve a stable increase in the support's height. If the required height adjustment is not achieved when the two height adjustment sliders are at their maximum distance from each other, the connection between the height adjustment base and the embedded plate must be loosened, height adjustment shims placed between them, and then the two height adjustment sliders adjusted to raise the support.

[0053] 3. This utility model utilizes the mutual movement of two wedge-shaped blocks and the placement of an adjustment pad to achieve the height adjustment function of the support; by connecting a hydraulic jack to the two wedge-shaped blocks, the height of the support can be adjusted without external assistance. This solution simplifies the height adjustment process, simplifies construction, and greatly improves the efficiency of support height adjustment. Attached Figure Description

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] Example 1

[0060] like Figures 1-3 As shown, this embodiment proposes a self-lifting height adjustment device for a tensile spherical force measuring support, including a height adjustment base and a height adjustment slider. The bottom surface of the height adjustment base is a plane, and the bottom surface of the height adjustment base is used to contact the top surface of the embedded plate 12 of the tensile spherical force measuring support. The height adjustment base is connected to the embedded plate 12 by bolt 607.

[0061] The top surface of the height-adjusting base is provided with a sliding groove, and the sliding groove has two inclined surfaces facing each other. A height-adjusting slider is placed on each of the two inclined surfaces. The bottom surface of the height-adjusting slider is an inclined surface and is adapted to the corresponding inclined surface. The height-adjusting slider can slide on the corresponding inclined surface. The top surface of the height-adjusting slider is a flat surface.

[0062] Preferably, the two inclined planes have the same inclination angle.

[0063] A telescopic component connects the two height-adjusting sliders, enabling the two sliders to slide synchronously along the inclined plane, move upwards or downwards simultaneously, achieving relative sliding between the two sliders within the groove. When the telescopic component extends, the two sliders move in opposite directions, sliding upwards along the inclined plane and increasing their height.

[0064] The self-lifting adjustment device 6 is used to be installed between the upper support plate 1 and the embedded plate 12 of the tensile ball-shaped force measuring support.

[0065] Preferably, the height-adjusting base includes a wedge plate 608, the top surface of which has two opposing inclined surfaces. Stoppers 606 are fixedly installed on both sides of the wedge plate 608, forming a groove between the stoppers 606 and the top surface of the wedge plate 608. The stoppers 606 are fixedly connected to the wedge plate 608 by bolts 605. The height-adjusting slider is a wedge block 604, and two wedge blocks 604 can slide within the groove on corresponding inclined surfaces. The telescopic component is a hydraulic jack 603, whose piston rod can extend and retract via a hydraulic system.

[0066] Before adjusting the height, disconnect the connection between the base plate 10 of the tensile spherical force measuring support and the embedded plate 12, loosen the lower anchor bolts 13 between the base plate 10 and the embedded plate 12, and the hydraulic jack 603 operates, pushing the two wedge blocks 604 on the wedge plate 608 to move away from each other (i.e., move in opposite directions) and slide along the inclined plane, thereby raising the height of the wedge blocks 604. The wedge blocks 604 lift the upper support plate 1. At the same time, since the upper support plate 1 of the tensile spherical force measuring support is connected to the base plate 10, the rise of the upper support plate 1 will drive the base plate 10 to rise together, thereby raising the height of the support. At this time, the base plate 10 and the embedded plate 12 are separated to leave a support space. An adjustment pad can be placed between the base plate 10 and the embedded plate 12 to achieve a stable increase in the height of the support.

[0067] If the required height adjustment is not achieved when the two wedge blocks 604 are at their maximum distance from each other, the bolt 607 connecting the wedge plate 608 and the embedded plate 12 needs to be loosened. After placing an adjustment shim between the wedge plate 608 and the embedded plate 12, the two wedge blocks 604 can be adjusted to raise the support. By continuously adjusting the distance between the two wedge blocks 604 with the hydraulic jack 603 and placing adjustment shims of different thicknesses, the height of the support can be easily and conveniently adjusted. Multiple stepless adjustments can be achieved, which can well meet the actual needs of the project, facilitate the actual construction operation, and realize height adjustment without external assistance.

[0068] This invention utilizes the mutual separation and proximity of two wedge blocks 604 and the placement of a height-adjusting pad to achieve the height adjustment function of the support. By connecting a hydraulic jack 603 to the two wedge blocks 604, the support can be adjusted in height without external assistance. This solution simplifies the height adjustment process, simplifies construction, and greatly improves the efficiency of support height adjustment. Its structure is simple and reliable.

[0069] Preferably, the wedge block 604 moves along the longitudinal direction of the bridge.

[0070] Preferably, the top and bottom surfaces of the wedge block 604 are respectively provided with wear-resistant plates 602, and the top and bottom surfaces of the wedge block 604 are respectively embedded in the corresponding wear-resistant plates 602.

[0071] Preferably, the wear-resistant plate 602 on the top surface of the wedge block 604 is slidably connected to the stainless steel plate 5 installed on the bottom surface of the upper support plate 1, and the wear-resistant plate 602 on the bottom surface of the wedge block 604 is slidably connected to the stainless steel plate 609 installed on the inclined surface, so that the wedge block 604 slides more smoothly in the groove and the support height adjustment is more convenient.

[0072] Preferably, a sealing ring 601 is installed between the top surface of the wedge block 604 and the upper support plate 1, and a sealing ring 601 is also installed between the bottom surface of the wedge block 604 and the inclined surface to achieve sealing of the sliding surface.

[0073] Example 2

[0074] like Figures 1-3 As shown, this embodiment proposes a tensile spherical force measuring support without external auxiliary height adjustment. Figures 1-3 This is also a structural diagram of a tensile spherical force-measuring support without external auxiliary height adjustment. The support includes, from top to bottom, an upper support plate 1, a spherical crown liner 7, a middle steel plate 8, a base plate 10, and an embedded plate 12. The spherical crown liner 7 and the middle steel plate 8 are located in a recessed cavity on the bottom surface of the upper support plate 1. A flat sliding plate 2 is installed between the upper support plate 1 and the spherical crown liner 7, and a spherical sliding plate 3 is installed between the spherical crown liner 7 and the middle steel plate 8. The middle steel plate 8 and the upper support plate 10 are connected in a series of steps. A guide slide plate 4 is installed between the support plates 1. A planar friction pair is formed between the upper support plate 1 and the spherical crown liner 7. A spherical friction pair is formed between the spherical crown liner 7 and the intermediate steel plate 8. A guide friction pair is formed between the intermediate steel plate 8 and the upper support plate 1. The tensile spherical force measuring support meets the requirements of support displacement and rotation angle through the planar friction pair, spherical friction pair and guide friction pair. Specifically, the rotation angle of the support is met by the rotation of the spherical crown liner 7 in the intermediate steel plate 8.

[0075] A force measuring element 11 is installed between the intermediate steel plate 8 and the base basin 10 to monitor the vertical bearing capacity of the support. The force measuring element 11 is existing technology and will not be described in detail here.

[0076] The upper support plate 1 and the basin ring of the bottom basin 10 are engaged through the contact of the tensile strip 9 to achieve the function of resisting pull-out. This design enables the support to withstand vertical pressure while effectively resisting the upward tensile force that the beam may generate, preventing the support from slipping out and maintaining the stability and safety of the structure.

[0077] The base plate 10 and the embedded plate 12 are connected by a lower anchor bolt 13.

[0078] Two sets of self-lifting devices 6 are symmetrically arranged between the upper support plate 1 and the embedded plate 12. Two wedge plates 608 are respectively arranged at both ends of the top surface of the embedded plate 12. The hydraulic jack 603 is arranged horizontally along the longitudinal direction of the bridge, and its two ends are respectively connected to the two wedge blocks 604.

[0079] The tensile ball-shaped force measuring support of this utility model is provided with a self-lifting height adjustment device 6 between the upper support plate 1 and the pre-embedded plate 12. The height adjustment function of the support is realized by the mutual separation and proximity of the two wedge blocks 604 and the placement of the height adjustment pad. The support can be adjusted without external assistance. The structure is simple and reliable and the operation is simple and convenient.

[0080] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
