Description

Technical Field

[0001] This utility model relates to the field of masonry handling technology, specifically a structural masonry construction handling tool. Background Technology

[0002] During the construction of block manholes, curbs, and other similar structures, frequent short-distance transportation, stacking, and installation of blocks and curbs are often required. Therefore, handling equipment is used.

[0003] For example, patent publication number CN212100499U discloses a simple masonry handling tool that is unlikely to damage the object being handled. This masonry handling tool includes two intersecting and hinged handling rods. The hinged portion of the handling rods is divided into a clamping section and a hand-held section, with the hand-held section being longer than the clamping section. A clamping block is fixedly installed at the end of the clamping section. The clamping blocks on the ends of the clamping sections of the two handling rods correspond to each other, and protective pads are provided on the corresponding sides of the two clamping blocks.

[0004] The above-mentioned device still has the following defects: two workers need to lift the handle section upwards with force. If one of them loses force slightly while walking, it will cause the handle section to hinge, which will cause the clamp to loosen. Therefore, the handling tool lacks a locking structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a structural masonry construction handling tool that incorporates a locking structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structural masonry construction handling tool, comprising two clamp handles connected to the outside of the masonry, thickened sleeves fixedly connected to the outer walls of the two clamp handles, a central shaft rotatably connected to the center of the two thickened sleeves, insert rods slidably connected to both ends of the central shaft, side ring blocks fixedly connected to the outer walls of the two thickened sleeves, slots corresponding to the positions of the insert rods being opened on the outer walls of the side ring blocks, movable grooves being opened at both ends of the central shaft, tension members being connected in both movable grooves, and a support rod structure being connected to the outer walls of the two side ring blocks.

[0007] Furthermore, the tensioning component includes a movable rod, the bottom surface of which is fixedly connected to a pulling spring, the other end of which is fixedly connected to the inner wall of the movable groove, the end of the movable rod away from the pulling spring being fixedly connected to a vertical plate, and the end of the insertion rod away from the slot being fixedly connected to the vertical plate.

[0008] Furthermore, the bracket structure includes an L-shaped tie rod and an L-shaped support plate. The L-shaped tie rod is rotatably connected to the side ring block. The L-shaped support plate has a groove, and the L-shaped tie rod is located in the groove and slidably connected to it. The outer wall of the L-shaped tie rod is connected to a fastening structure.

[0009] Furthermore, the fastening structure includes a slide rod and a threaded ring. The outer wall of the L-shaped receiving plate has a side groove that communicates with the pull groove. The outer wall of the L-shaped pull rod is fixedly connected to the slide rod. The slide rod is slidably connected to the side groove. The outer side of the slide rod passing through the side groove has an external thread. The outer thread of the slide rod is connected to a threaded ring.

[0010] Furthermore, the outer wall of the threaded ring is provided with anti-slip texture.

[0011] Furthermore, a lever is fixedly connected to the top of the vertical plate.

[0012] Furthermore, an installation block is fixedly connected to the outer wall of the side ring block, and a rotating groove is opened in the installation block. An end block is fixedly connected to the end of the L-shaped tie rod away from the L-shaped support plate. The end block is rotatably connected to the rotating groove. Two symmetrically arranged jacking springs are fixedly connected to the top surface of the end block. The other ends of the two jacking springs are fixedly connected to the inner wall of the rotating groove.

[0013] Furthermore, the end of the insertion rod located inside the slot is chamfered.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model, through the cooperative arrangement of a thickened sleeve, side ring blocks, insert rods, and slots, ensures that the central shaft and the side ring blocks at both ends cannot rotate relative to each other. This allows the central shaft to limit and fix the thickened sleeve and handle. The multiple slots allow for multi-angle limitation after the clamp handle rotates to accommodate masonry of different thicknesses. The limiting range can be adjusted according to the different hinge angles of the handling tool itself. This structure is simple, easy to operate, and highly practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 5 As shown, a structural masonry construction handling tool includes two clamp handles 1 connected to the outside of the masonry. The outer walls of the two clamp handles 1 are fixedly connected to thickened sleeves 2. The two thickened sleeves 2 are rotatably connected to a central shaft 4. The two ends of the central shaft 4 are slidably connected to insert rods 15. The outer walls of the two thickened sleeves 2 are fixedly connected to side ring blocks 7. The outer walls of the side ring blocks 7 are provided with slots 16 corresponding to the positions of the insert rods 15. The two ends of the central shaft 4 are provided with moving grooves 10. The two moving grooves 10 are connected to tension members. The outer walls of the two side ring blocks 7 are connected to a support rod structure.

[0024] like Figure 1 As shown, the structural masonry construction handling tool in this utility model is structurally similar to existing masonry handling tools, such as the masonry handling tool disclosed in patent publication number CN212100499U. The main improvement of this utility model is that the handling tool has a locking structure, such as... Figures 1 to 5 As shown, when the masonry construction handling tool of this utility model is in use, when the masonry is being clamped, the clamping section at the lower end of the clamp handle 1 can be clamped to the masonry. At this time, the clamp handles 1 are brought close to each other to clamp the clamping section. Then, the insert rod 15 is inserted into the slot 16, so that the central shaft 4 and the two side ring blocks 7 cannot rotate relative to each other. Since the side ring blocks 7, the thickened sleeve 2, and the handle are all fixedly connected, the clamping section of the clamp handle 1 will not rotate and separate, so that the two clamping sections are locked.

[0025] By cooperating with the thickened sleeve 2, the side ring block 7, the insert rod 15, and the slot 16, the central shaft 4 and the side ring blocks 7 at both ends can be made to be unable to rotate relative to each other. Thus, the central shaft 4 can limit and fix the thickened sleeve 2 and the handle. The slot 16 is set in multiple ways, which can be used to deal with masonry of different thicknesses. The clamp handle 1 can be limited at multiple angles after rotation, so that the limiting range can be limited according to the different hinge angles of the handling tool itself.

[0026] like Figure 2 and Figure 3 As shown, the tensioning component includes a moving rod 12, a pulling spring 11 is fixedly connected to the bottom surface of the moving rod 12, the other end of the pulling spring 11 is fixedly connected to the inner wall of the moving groove 10, a vertical plate 13 is fixedly connected to the end of the moving rod 12 away from the pulling spring 11, and the end of the insert rod 15 away from the slot 16 is fixedly connected to the vertical plate 13.

[0027] Specifically, when the insertion rod 15 needs to be inserted into the slot 16, the vertical plate 13 can be pulled to move the moving rod 12 within the moving groove 10. At this time, the pulling spring 11 is stretched. After the insertion rod 15 is inserted into the corresponding slot 16, the insertion rod 15, under the contraction action of the pulling spring 11, directly pulls the moving rod 12 to drive the vertical plate 13 and the insertion rod 15 into the slot 16.

[0028] By pulling the spring 11, the insertion of the rod 15 into the slot 16 can be stabilized.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the support rod structure includes an L-shaped tie rod 6 and an L-shaped support plate 5. The L-shaped tie rod 6 is rotatably connected to the side ring block 7. The L-shaped support plate 5 has a groove 17. The L-shaped tie rod 6 is located in the groove 17 and is slidably connected to it. The outer wall of the L-shaped tie rod 6 is connected to a fastening structure.

[0030] Specifically, after the handling tool is clamped to the masonry, the worker can rotate the L-shaped tie rod 6 to the side closer to the masonry. Before that, the distance between the L-shaped tie rod 6 and the L-shaped support plate 5 can be adjusted so that the bottom of the L-shaped support plate 5 can be in contact with the bottom surface of the masonry. Then, the position of the L-shaped support plate 5 after the distance adjustment is completed is fixed by the fastening structure.

[0031] At this point, the worker can lift the handle 1 of the hand clamp, so that the L-shaped receiving plate 5 rotates under the action of gravity to receive the bottom of the masonry. This disperses the force to a certain extent while receiving the bottom of the masonry.

[0032] like Figure 2 and Figure 4As shown, the fastening structure includes a slide rod 9 and a threaded ring 3. The outer wall of the L-shaped receiving plate 5 is provided with a side groove 18 that communicates with the pull groove 17. The outer wall of the L-shaped pull rod 6 is fixedly connected to the slide rod 9. The slide rod 9 is slidably connected to the side groove 18. The outer side of the slide rod 9 that passes through the side groove 18 is provided with an external thread. The outer side of the slide rod 9 is threadedly connected to the threaded ring 3.

[0033] Specifically, when it is necessary to adjust the distance of the L-shaped receiving plate 5, rotate the threaded ring 3 to loosen its inner wall from the outer wall of the L-shaped receiving plate 5, and then slide the L-shaped receiving plate 5 so that the slide rod 9 slides in the side groove 18. After moving to the position, directly rotate the threaded ring 3, and through the compression of the threaded ring 3, fix the L-shaped receiving plate 5 on the outer wall of the L-shaped tie rod 6.

[0034] like Figure 4 As shown, the outer wall of the threaded ring 3 is provided with anti-slip texture. The anti-slip texture facilitates the rotation of the threaded ring 3.

[0035] like Figure 3 As shown, a lever 14 is fixedly connected to the top of the vertical plate 13. The lever 14 is designed to facilitate pulling the vertical plate 13.

[0036] like Figure 4 and Figure 5 As shown, an installation block 8 is fixedly connected to the outer wall of the side ring block 7. A rotating groove 21 is opened in the installation block 8. An end block 19 is fixedly connected to the end of the L-shaped tie rod 6 away from the L-shaped support plate 5. The end block 19 is rotatably connected to the rotating groove 21. Two symmetrically arranged jacking springs 20 are fixedly connected to the top surface of the end block 19. The other end of the two jacking springs 20 is fixedly connected to the inner wall of the rotating groove 21.

[0037] Specifically, to prevent the L-shaped tie rod 6 from failing to rotate under gravity, two jacking springs 20 are installed on the top surface of the end block 19. When the masonry is on the ground, the clamping section of the clamp handle 1 has already clamped the masonry, and the L-shaped support plate 5 can only support the ground at its end under the action of the jacking springs 20. Once the masonry is lifted by the handling tool, the L-shaped support plate 5 will directly rotate and support the bottom surface of the masonry under the action of the jacking springs 20.

[0038] like Figure 3 As shown, one end of the insertion rod 15 located inside the slot 16 is chamfered. The chamfer helps guide the insertion rod 15 when it is inserted into the slot 16.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
