Description

Technical Field

[0001] This utility model relates to a wrench, and more particularly to a wrench specifically designed for maintenance in confined spaces, belonging to the field of maintenance tool technology. Background Technology

[0002] In on-site embedded component construction scenarios such as power transmission and transformation projects, embedded components are mostly made of galvanized steel plates, which are quite thick and require extremely high precision in installation elevation, necessitating strict control of the error range. Currently, the positioning, installation, and elevation adjustment of embedded components on-site still rely on the traditional manual method of directly adjusting the embedded components by hand. When faced with confined working spaces, the handling of embedded components is obstructed, making it difficult to quickly and accurately position them. The tools used are also poorly adaptable. Furthermore, during the process of manually moving and adjusting the elevation, the embedded components are prone to displacement. This not only makes the operation difficult and inefficient but also fails to meet the millimeter-level precision control requirements, directly affecting the construction quality and overall progress, and causing numerous inconveniences to on-site embedded component construction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a special wrench for maintenance in a confined space, which can effectively overcome the defects of the prior art, realize the rapid and accurate maintenance of embedded parts, and significantly improve maintenance efficiency and quality.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A wrench specifically designed for maintenance in confined spaces includes a pressure-bearing base with a protective square steel plate on it. An opening on one side of the protective square steel plate allows for the entry, exit, and longitudinal movement of an embedded part. An adjustment structure is located at the end of the protective square steel plate away from the pressure-bearing base to drive the embedded part for height adjustment. The adjustment structure includes a support member positioned on the protective square steel plate corresponding to the opening for placing the embedded part, and a drive assembly located at the end of the protective square steel plate away from the pressure-bearing base for driving the support member to move longitudinally along the protective square steel plate.

[0005] The support member includes a support panel that moves longitudinally on the protective square steel at the opening position to place the embedded part, and a connecting rod that is fixedly connected to the bottom of the support panel and connected to the drive assembly.

[0006] The drive assembly includes a bolt cap rotatably connected to the end of the protective square steel away from the pressure-bearing base, and a screw rod that runs longitudinally through the protective square steel and is screwed to the bolt cap. The end of the screw rod away from the bolt cap is fixedly connected to the end of the connecting rod away from the support panel.

[0007] A handle is fixedly connected to the end of the bolt cap away from the protective square steel.

[0008] The minimum height difference between the end of the screw near the connecting rod and the end face of the protective square steel is 0.04mm-0.05mm.

[0009] The protective square steel is fixedly equipped with scales on both sides of the corresponding opening to display the height position of the support panel and embedded parts.

[0010] The positive and beneficial effects of this utility model are: 1. This utility model solves the problem of obstructed loading and unloading of embedded parts by protecting the square steel with a single-sided opening design, allowing the embedded parts to be quickly moved in and out and positioned, adapting to the needs of restricted working environments.

[0011] 2. This utility model forms a stable support structure through the pressure-bearing base and the protective square steel, and with the direct bearing of the bearing component and the directional drive of the drive component, the overall structure is simple and small in size, which is convenient for installation and operation in narrow positions. Therefore, it does not require a lot of manpower and materials, reduces the difficulty of operation in narrow spaces, and effectively reduces the ineffective consumption in the operation process, thereby improving the operation efficiency of embedded part positioning and installation.

[0012] 3. This utility model, by setting a scale, can synchronize with the lifting trajectory of the support panel, so that the operator can directly read the real-time height position of the support panel and the embedded part through the scale, without the need for additional measuring tools, thus saving the tedious steps of additional measurement in a confined space, realizing intuitive and accurate control of the height of the embedded part, and improving the accuracy and work efficiency of the embedded part positioning and installation.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a side view of the present invention. Figure 3 This is a schematic diagram of the structure of the bolt cap of this utility model; Among them: 1-pressure bearing base, 2-protective square steel, 21-scale, 3-opening, 4-adjustment mechanism, 41-bearing component, 411-support panel, 412-connecting rod, 42-drive assembly, 421-bolt cap, 422-screw, 423-handle. Detailed Implementation

[0014] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-3A special wrench for maintenance in confined spaces includes a pressure base 1, a protective square steel 2 fixedly connected to the pressure base 1, an opening 3 on one side of the protective square steel 2 for the entry, exit and longitudinal movement of embedded parts, and an adjustment structure 4 located at the end of the protective square steel 2 away from the pressure base 1 for driving the embedded parts to adjust their height. The adjustment structure 4 includes a carrier 41 located on the protective square steel 2 at the position corresponding to the opening 3 for placing the embedded parts, and a drive assembly 42 located at the end of the protective square steel 2 away from the pressure base 1 for driving the carrier 41 to move longitudinally along the protective square steel 2.

[0015] In use, first place the pressure base 1 stably in the work area to provide stable support. After the protective square steel 2 is fixed in place with the pressure base 1, put the embedded part to be inspected or installed into the opening 3 on one side of the protective square steel 2 and place it on the bearing 41 to complete the quick positioning and placement of the embedded part. Then, operate the drive component 42 at the end of the protective square steel 2 away from the pressure base 1. The drive component 42 generates driving force and acts on the bearing 41, driving the bearing 41 to move longitudinally along the protective square steel 2, thereby driving the embedded part to rise and fall synchronously until the embedded part is adjusted to the required height, and finally realize the precise positioning and inspection of the embedded part in a narrow space.

[0016] Specifically, the support member 41 includes a support panel 411 that moves longitudinally to the position corresponding to the opening 3 on the protective square steel 2 for placing the embedded part, and a connecting rod 412 that is fixedly connected to the bottom of the support panel 411 and connected to the drive assembly 42. First, the embedded part is placed stably on the support panel 411, which directly bears the weight of the embedded part and provides stable support. When the drive component 42 is started, the driving force generated is transmitted to the connecting rod 412 which is fixedly connected to the bottom of the support panel 411. The connecting rod 412 transmits the driving force to the support panel 411, causing the support panel 411 to move longitudinally along the protective square steel 2, thereby realizing the smooth lifting and directional movement of the embedded part and ensuring the accurate positioning of the embedded part in a narrow space.

[0017] Furthermore, the drive assembly 42 includes a bolt cap 421 rotatably connected to the end of the protective square steel 2 away from the pressure base 1, and a screw 422 that runs longitudinally through the protective square steel 2 and is screwed to the bolt cap 421. The end of the screw 422 away from the bolt cap 421 is fixedly connected to the end of the connecting rod 412 away from the support panel 411. A handle 423 is fixedly connected to the end of the bolt cap 421 away from the protective square steel 2. The operator holds the handle 423 and applies rotational force. Since the handle 423 and the bolt cap 421 are fixed, rotating the handle 423 can synchronously drive the bolt cap 421 to rotate around the end of the protective square steel 2 away from the pressure base 1. Since the screw 422 longitudinally penetrates the protective square steel 2 and is screwed to the bolt cap 421, the rotational motion of the bolt cap 421 is converted into the longitudinal linear motion of the screw 422. The end of the screw 422 away from the bolt cap 421 is fixedly connected to the end of the connecting rod 412 away from the support panel 411. The support panel 411 moves longitudinally along the protective square steel 2, and then the connecting rod 412 moves synchronously through the lifting and lowering of the screw 422, ultimately realizing the height adjustment of the support panel 411 and the embedded part.

[0018] In addition, to ensure the effective stroke of the embedded part height adjustment, the minimum height difference between the end of the screw 422 near the connecting rod 412 and the end face of the protective square steel 2 is 0.04mm-0.05mm. By maintaining a minimum height difference of 0.04mm-0.05mm between the end of the screw 422 near the connecting rod 412 and the end face of the protective square steel 2, basic movement space is reserved for the screw 422. This ensures that when the screw 422 moves longitudinally under the action of the drive assembly 42, it will not rub against the end face of the protective square steel 2 and get stuck. At the same time, it meets the minimum adjustment stroke requirement, thereby avoiding the problem of jamming or insufficient adjustment stroke during the lifting and lowering of the screw 422, ensuring the smoothness and effective range of the embedded part height adjustment, and improving the reliability of the device. Example

[0019] Unlike Embodiment 1, in order to achieve visual and precise adjustment of the height of the embedded part, the protective square steel 2 is fixedly provided with a scale 21 on both sides of the opening 3 to display the height position of the support panel 411 and the embedded part. Initially, the scale markings on the ruler 21 are synchronized with the longitudinal movement trajectory of the support panel 411. When the drive component 42 drives the connecting rod 412 and then drives the support panel 411 to move up and down longitudinally along the protective square steel 2, the embedded part placed on the support panel 411 moves synchronously with the support panel 411. The operator can directly read the real-time height value of the embedded part by observing the corresponding position of the edge of the support panel 411 and the scale of the ruler 21. The height of the embedded part can be accurately controlled without additional measuring tools, realizing the visual and precise positioning and adjustment of the embedded part in a narrow space.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
