Description

Technical Field

[0001] The utility model relates to the technical field of maintenance auxiliary devices, in particular to a balance beam for a lock maintenance gate. Background Technique

[0002] As a key facility for water transportation, the normal operation of a lock is crucial for ensuring that ships can smoothly pass through the water level drop on the waterway. Since the lock is in an underwater working environment for a long time and needs to frequently raise and lower the water level to meet the passage needs of different ships, its structure and equipment will be subject to certain wear and corrosion. In order to ensure the safe operation of the lock and extend its service life, regular maintenance and repair are essential.

[0003] Generally, when it is necessary to open the lower lock head maintenance gate during maintenance, an L-shaped gantry crane is used to lift the lock. In order to ensure the balance when the gate is lifted and reduce the horizontal pressure borne by the L-shaped gantry crane, a balance beam is connected between the sling of the L-shaped gantry crane and the gate.

[0004] However, the applicant found on site that since the connection point between the sling of the L-shaped gantry crane and the balance beam is a single lifting point, when the balance beam enters the gate slot to grab the gate underwater, it is easy to cause a large deviation in the horizontal level at both ends and it is difficult to insert the pin into position. Even unilateral pin insertion may occur, resulting in damage to the pin shaft and the gate pin hole, and the maintenance gate cannot be opened normally, seriously affecting the construction safety and progress of lock maintenance and lock temporary inspection. Content of the Utility Model

[0005] The utility model provides a balance beam for a lock maintenance gate, and the technical problem to be solved is to be able to adjust the weights at both ends of the balance beam.

[0006] To solve the above technical problem, the utility model adopts the following technical scheme:

[0007] A balance beam for a lock maintenance gate includes a balance beam main body. A lifting ring for connecting with a crane sling is arranged at the upper end of the balance beam main body, and a pin shaft for connecting with the gate is arranged at the lower end. It further includes an adjusting assembly. The adjusting assembly includes a stud, a nut and a counterweight block. One end of the stud is connected to the balance beam main body. The counterweight block is detachably sleeved on the stud, and the nut is threadedly connected to the stud and blocks the upper end of the counterweight block.

[0008] As a further improvement of the above technical scheme:

[0009] In at least one embodiment, guiding supports are arranged at both ends of the balance beam main body. The guiding supports are in an "H" shape, and guiding wheels are arranged in the grooves on the outer sides of the guiding supports.

[0010] Compared with the prior art, the utility model at least achieves the following beneficial effects: For the balance beam of a maintenance gate of a ship lock in the utility model, when it is found that the horizontal deviation at both ends of the balance beam body is relatively large, the weight of the lighter end can be increased or the weight of the heavier end can be reduced, thereby reducing the horizontal deviation at both ends of the balance beam body, and ensuring that the balance beam and the gate can be smoothly pinned in place.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present application will be described in detail below with reference to the exemplary embodiments in the drawings. However, it should be understood that the present application can be implemented in various different forms and should not be construed as limited to the embodiments described herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0018] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application.

[0019] In view of the defect in the prior art that the horizontal deviation at both ends of the balance beam is large, making it difficult to insert the pin into position, and even unilateral pin insertion occurs, resulting in damage to the pin shaft and the gate pin hole, and the maintenance gate cannot be opened normally. After careful analysis, the inventor found that the main reason for the above problems in the existing balance beam is that the connection point between the suspension cable of the L-shaped gantry crane and the balance beam is a single suspension point, and the position may deviate slightly during each installation, resulting in a large horizontal deviation at both ends of the balance beam and making it difficult to insert the pin into position. Based on the above analysis, the inventor made a structural improvement to both ends of the balance beam.

[0020] As Figures 1-4 shown, a balance beam for a ship lock maintenance gate in the present application includes a balance beam main body 1 and an adjustment assembly 2. By means of the adjustment assembly 2, the weights at both ends of the balance beam main body 1 can be adjusted, the horizontal deviation when the balance beam enters the gate slot can be reduced, and thus the smooth insertion of the pin between the balance beam and the gate can be ensured.

[0021] Embodiment 1

[0022] Among them, referring to Figure 1 and Figure 2 , a suspension ring 11 for connecting with the crane suspension cable is arranged at the upper end of the balance beam main body 1, and a pin shaft 12 for connecting with the gate is arranged at the lower end.

[0023] Furthermore, guiding supports 13 are arranged at both ends of the balance beam main body 1. Among them, the cross-section of the guiding support 13 is in the shape of "H", with a height of about two meters. Guide wheels 14 are arranged in the grooves on the outer side of the guiding support 13, and two groups of guide wheels 14 are arranged at intervals along the height direction of the guiding support 13.

[0024] By means of the guiding supports 13 arranged at both ends of the balance beam main body 1 and the guide wheels 14 arranged at intervals along the height direction of the guiding support, a double-wheel guiding can be formed when the balance beam enters the gate slot, further reducing the horizontal deviation when the balance beam enters the gate slot, ensuring the smooth insertion of the pin between the balance beam and the gate, eliminating potential safety hazards, improving the operation efficiency, and further avoiding the risk of equipment damage and inability to open the maintenance gate caused by unilateral pin insertion.

[0025] Furthermore, reinforcing ribs 15 are provided on the inner side of the guiding support 13. Both ends of the reinforcing ribs 15 are fixedly connected to the guiding support 13 and the main body 1 of the balance beam respectively. The rigidity of the guiding support 13 can be increased through the reinforcing ribs 15, avoiding deformation of the guiding support 13 with a relatively high height after multiple uses, and further reducing the guiding effect on the balance beam when entering the gate slot.

[0026] Furthermore, connecting frames 16 are provided on both sides of the upper end of the main body 1 of the balance beam. One ends of the connecting frames 16 on both sides are fixedly connected to the main body 1 of the balance beam, and the other ends are inclined upward towards the inner side and intersect at the upper end of the middle part of the main body 1 of the balance beam. The lifting ring 11 is fixedly arranged at the intersection of the connecting frames 16 on both sides. By fixedly arranging the lifting ring 11 at the intersection of the connecting frames 16 on both sides, the horizontal distance of the lever arm between both ends of the main body 1 of the balance beam and the lifting ring 11 can be reduced, and further the problem of large deviation in the levelness of both ends of the main body 1 of the balance beam caused by the installation error of the sling on the lifting ring 11 can be reduced.

[0027] Furthermore, fences 17 are provided on the connecting frames 16. In order to install or disassemble the sling, installers need to climb onto the connecting frames 16. In order to ensure the personal safety of the installers, fences 17 are provided on both sides of the connecting frames 16 to reduce the risk of falling.

[0028] Among them, referring to Figure 2 , the adjusting assembly 2 includes a stud 21, a nut 22 and a counterweight 23. One end of the stud 21 is connected to the main body 1 of the balance beam. The counterweight 23 is detachably sleeved on the stud 21. The nut 22 is threadedly connected to the stud 21 and blocks the upper end of the counterweight 23. After rotating the nut 22, the nut 22 can press the counterweight 23 against the main body 1 of the balance beam.

[0029] Optionally, the counterweight 23 has multiple specifications. The thicknesses of the counterweights 23 with different specifications are different, so the weights of the counterweights 23 with different specifications are different. Weight data is marked on the counterweight 23 so that installers can select counterweights 23 with different specifications according to needs.

[0030] In the first embodiment, in order to increase the adjustment range, three groups of studs 21 are provided at one end of the main body 1 of the balance beam. The three groups of studs 21 are arranged at intervals along the length direction of the main body 1 of the balance beam, and the lower ends are all fixedly connected to the main body 1 of the balance beam. Therefore, the horizontal distance of the lever arm between each group of studs 21 and the lifting ring 11 is different, and a larger adjustment range can be obtained under the condition of the same number of configuration blocks. And, aiming at the problems existing in the construction site, the solution provided in the first embodiment can facilitate the improvement of the balance beam used on site.

[0031] During use, before the balance beam enters the gate slot, if it is found that the horizontal deviation at both ends of the balance beam body 1 is relatively large, the weight block 23 at the lighter end can be increased or the weight block 23 at the heavier end can be reduced, thereby reducing the horizontal deviation at both ends of the balance beam body 1, ensuring that the balance beam and the gate can be smoothly pinned in place, eliminating potential safety hazards, improving the operation efficiency, and further avoiding the risks of equipment damage caused by unilateral pinning and the inability to open the maintenance gate.

[0032] Embodiment 2

[0033] Among them, referring to Figure 3 and Figure 4 , the adjusting assembly 2 includes a stud 21, a nut 22 and a weight block 23. One end of the stud 21 is connected to the balance beam body 1. The weight block 23 is detachably sleeved on the stud 21. The nut 22 is threadedly connected to the stud 21 and blocks the upper end of the weight block 23. After rotating the nut 22, the nut 22 can press the weight block 23 against the balance beam body 1.

[0034] Different from the above Embodiment 1, in this Embodiment 2, referring to Figure 4 , a block 211 is provided at the lower end of the stud 21, and a sliding groove 18 is provided at the upper end of the balance beam body 1. The block 211 is slidably arranged in the sliding groove 18. Further, a scale line 19 is arranged along the length direction of the sliding groove 18 at the upper end of the balance beam body 1.

[0035] In this Embodiment 2, through the slidable connection between the block 211 at the lower end of the stud 21 and the sliding groove 18, the horizontal distance of the lever arm between the stud 21 and the lifting ring 11 can be linearly adjusted. After adjustment, the nut 22 can be tightened so that the nut 22 presses the weight block 23 against the balance beam body 1, thereby relatively fixing the stud 21 and the balance beam body 1.

[0036] It should be understood that all the above embodiments are exemplary rather than restrictive. Those skilled in the art, under the concept of the present invention, make various modifications or deformations to the specific embodiments described above, and all should be within the protection scope of the present invention.
