Description

Technical Field

[0001] This utility model relates to the field of distance measurement technology, and specifically to an anti-deflection mounting mechanism for bidirectional measuring equipment. Background Technology

[0002] Gate hoists, also known as gate hoists, are a type of large-scale hydraulic machinery. Gate hoists are crucial to the normal operation of hydraulic structures. In addition to meeting the design requirements of general lifting machinery, they are of special significance in terms of safe and reliable operation and flexible and convenient operation.

[0003] Patent CN118243039B discloses a bidirectional measuring device and a gate opening / closing mechanism incorporating the bidirectional measuring device, which can perform both gate position measurement and stroke measurement. However, the following problems still exist during its assembly:

[0004] During assembly, the drive shaft carrier needs to be placed on the base first, and then connected to the threaded hole in the base by screws through the slot. However, during the assembly process, the drive shaft carrier is easily misaligned relative to the base due to external forces, which will affect the subsequent assembly process such as the installation of the secondary gear and the meshing connection between the secondary gear and the drive gear. Utility Model Content

[0005] In view of this, the problem to be solved by this utility model is to provide an anti-deflection mounting mechanism for bidirectional measuring equipment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] The anti-skew mounting mechanism for bidirectional measuring equipment has a lower convex clamp at the bottom of the drive shaft carrier and an upper convex support frame inside the base. The spacing between adjacent upper convex support frames corresponds to the width of the lower convex clamp. The lower convex clamp can be inserted between adjacent lower convex clamps and cannot rotate relative to each other.

[0008] The transverse cross-section of the convex card body is a rectangular structure.

[0009] The drive shaft carrier has a strip-shaped through slot, and the upper convex support frame has an internal threaded groove I at the position corresponding to the strip-shaped through slot.

[0010] The strip-shaped through groove and the internal threaded groove I are located at the middle position of the drive shaft carrier and the base.

[0011] The upper convex support frame has an n-shaped structure, and the contact ends where the drive shaft carrier and the upper convex support frame abut are both flat.

[0012] The convex lower clip is suspended inside the base.

[0013] The base has several ventilation holes.

[0014] The advantages and positive effects of this utility model are:

[0015] An upper protruding support frame and a lower protruding clamp are respectively provided on the base and the drive shaft carrier. The lower protruding clamp can be inserted between adjacent upper protruding support frames, and the structural design of the lower protruding clamp is such that it cannot rotate relative to the upper support frame after insertion. Therefore, when the drive shaft carrier is installed, even if it is subjected to external force, it will not deflect relative to the upper support frame due to the mutual limiting effect of the lower protruding clamp and the upper support frame.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 3 As shown, this utility model provides:

[0028] For the anti-deflection mounting mechanism of bidirectional measuring equipment, the bottom of the drive shaft carrier 1 has a lower protruding clip 11, and the base 2 has an upper protruding support frame 21 inside. The spacing between adjacent upper protruding support frames 21 corresponds to the width of the lower protruding clip 11. In this embodiment, two upper protruding support frames 21 are provided, and the lower protruding clip 11 is inserted between adjacent upper protruding support frames 21. The structural shape of the lower protruding clip 11 is such that it cannot rotate relative to each other after insertion. Therefore, when installing the drive shaft carrier 1, even if it is subjected to external force, relative deflection will not occur due to the mutual limiting effect of the lower protruding clip 11 and the upper protruding support frame 21. The strip groove 12 of the drive shaft carrier 1 is directly aligned with the internal thread groove 22 of the upper protruding support frame 21, and then fixedly connected by screws 3.

[0029] Specifically, the lower convex card body 11 has a rectangular cross-section, and a corresponding strip slot is formed between adjacent upper convex support frames 21. This allows for relative positioning between the upper convex card body 11 and the lower convex card body 11 when subjected to external force, preventing relative rotation between the two.

[0030] Specifically, the drive shaft carrier 1 has a strip-shaped through slot 12, and the upper convex support bracket 21 has an internal threaded groove 22 at the position corresponding to the strip-shaped through slot 12. This design allows the position of the internal threaded groove 22 to be directly seen through the strip-shaped through slot 12 after the lower convex clip 11 is inserted between the adjacent upper convex support brackets 21, thus enabling quick determination of the fixing hole position. During installation, the screw 3 is threaded through the strip-shaped through slot 12 and then threaded into the internal threaded groove 22. The screw 3 does not need to have an excessively long stroke, which also ensures the stability during the tightening process.

[0031] Specifically, the strip groove 12 and the internal thread groove 22 are located at the middle position of the drive shaft carrier 1 and the base 2, so that the upper convex support frame 21 is supported at the center position of the drive shaft carrier 1, and the drive shaft carrier 1 is prevented from tilting due to excessive center of gravity after being placed on the upper convex support frame 21.

[0032] Specifically, the upper convex support frame 21 has an n-shaped structure, which can reduce its own weight while achieving the supporting function, making the whole machine lightweight; the contact ends of the drive shaft carrier 1 and the upper convex support frame 21 are flat, avoiding the height difference between the two after they come into contact.

[0033] like Figures 4 to 5 As shown, specifically, the lower protruding clip 11 is suspended inside the base 2, leaving a gap between the lower protruding clip 11 and the inner bottom surface of the base 2. This space can be used as a wiring area. That is, after the wire is connected to the limit switch group 5 on the drive shaft carrier 1, it passes through this wiring area and the cable groove 24 on the side of the base 2 to connect to the external power supply. This design allows the wire to be arranged through the bottom of the drive shaft carrier 1, separating the wire from the moving components. This not only avoids the wire from getting tangled during operation of the moving components such as the drive shaft 23 on the drive shaft carrier 1, but also makes the wiring inside the machine neater.

[0034] Specifically, the base 2 is provided with several ventilation holes 4. In this embodiment, the ventilation holes 4 are located at the bottom of the base 2. When liquid substances enter the whole machine, they can be quickly discharged under the action of gravity.

[0035] like Figures 6 to 7 As shown, further considering that the existing bidirectional measuring equipment requires drilling holes in the gate hoist support frame during installation and then connecting it with bolts, drilling is time-consuming and labor-intensive, increasing the workload of workers, and also reducing the structural strength of the gate hoist support frame.

[0036] Therefore, this technical solution also proposes a connection frame 8 that can be installed without drilling, including an n-shaped support part 81 and a horizontal plate part 82 constructed below the support part 81. A connecting through groove 85 is provided on the top of the support part 81, and a threaded groove corresponding to the fastening bolt I83 is provided on the outer bottom surface of the base 2. The threaded part of the fastening bolt I83 passes through the connecting through groove 85 and connects with the threaded groove on the base 2, thereby realizing a fixed connection with the base 2. The two sets of horizontal plate parts 82 extend along the inner side of the support part 81, and a gap 84 is left between the two sets of horizontal plate parts 82.

[0037] The fastening bolt I83 is a fastener used in the prior art to fix the cover plate of the gate hoist. It is an inherent structure on the gate hoist. When the connecting frame 8 needs to be connected to the gate hoist, one of the fastening bolts I83 on the cover plate 91 is first turned in the reverse direction so that the stud part of the fastening bolt I83 is exposed outside the cover plate 91. Then, through the gap 84 between the two sets of horizontal plate parts 82 on the connecting frame 8, the connecting frame 8 is inserted into the stud part in the radial direction of the stud part of the fastening bolt I83. Then, a wrench is inserted into the inside of the connecting frame 8 and the fastening bolt I83 is turned in the forward direction so that the stud part of the fastening bolt I83 gradually enters into the cover plate 91. Then, the nut of the fastening bolt I83 moves in the direction close to the horizontal plate part 82 until it is tightly abutted against the horizontal plate part 82 near the gap 84, thereby realizing the fixed connection between the connecting frame 8 and the gate hoist.

[0038] Specifically, the width of the gap 84 is greater than the width of the stud portion of the bolt I83 and less than the width of the nut portion of the fastening bolt I83.

[0039] The working principle and process of this utility model are as follows:

[0040] When installing the drive shaft carrier 1, the lower protruding clip 11 at the bottom of the drive shaft carrier 1 is inserted into the area between the two upper protruding support brackets 21 on the base 2. The other areas at the bottom of the drive shaft carrier 1 abut against the top of the upper protruding support bracket 21. When subjected to external force, the upper protruding support bracket 2 can achieve relative limiting between itself and the lower protruding clip 11 to prevent relative rotation between the two. The strip through groove 12 directly shows the position of the internal thread groove 22, realizing the quick determination of the fixing hole position. The threaded part of the screw 3 passes through the strip through groove 12 and then connects to the internal thread groove 22 by thread, realizing the fixed connection between the drive shaft carrier 1 and the base 2.

[0041] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
