Description

Technical Field

[0001] The utility model relates to the technical field of columns, in particular to a column with a connection and tightening function. Background Art

[0002] Guardrails generally consist of columns, handrails, and crossbars, which can play a corresponding blocking and protective role. At present, various metal guardrails formed by connecting steel wire ropes between the columns on both sides are widely used because of their easy installation and good impact resistance. However, most of the existing columns do not have the function of connecting and tightening the steel wire rope. Therefore, during the installation and construction, it is usually necessary to use corresponding tensioners to connect and tighten the two ends of the steel wire rope respectively, and apply a certain pre-tensioning force. Since multiple steel wire ropes are usually arranged at intervals along the height direction of the column, the number of tensioners that need to be installed is also relatively large, which will increase the cumbersomeness of the overall installation steps to a certain extent. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a column with a connection and tensioning function, which can simultaneously tension multiple steel ropes without using corresponding tensioners and play a corresponding connection and tensioning role, thereby reducing the cumbersomeness of the overall installation steps to a certain extent.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a column with a connecting and tensioning function, including a column body, a tensioning plate and a tensioning drive mechanism. An upwardly open cavity is provided in the column body, and two symmetrical and longitudinally arranged partitions are fixedly provided in the cavity. The two partitions divide the cavity into a limited position cavity and two tensioning cavities. The limited position cavity is arranged between the two tensioning cavities. The two tensioning cavities are both provided with a longitudinally arranged and liftable tensioning plate. The left and right side surfaces of the column body, the partitions and the tensioning plates are all provided with a plurality of longitudinally spaced mounting holes. A tensioning drive mechanism is provided in the two tensioning cavities. The tensioning drive mechanism is used to drive the tensioning plate to rise and fall and make the mounting holes on the tensioning plate staggered with the mounting holes on the column body and the partitions.

[0005] Furthermore, guide blocks are fixedly provided at both upper and lower ends of the tensioning plate. The guide blocks are in a rectangular shape and are adapted to the tensioning cavity. The guide blocks are embedded in the tensioning cavity and the two slide up and down in cooperation.

[0006] Furthermore, the tensioning drive mechanism includes an adjusting bolt, a compression spring and a limit block. The limit block is arranged above the tensioning plate and is detachably installed at the upper end opening of the tensioning cavity through a locking device. The compression spring is arranged below the tensioning plate. The limit block is provided with a first threaded hole that is compatible with the adjusting bolt. The adjusting bolt is threadedly connected in the first threaded hole and the end of the screw rod thereof is abutted against the guide block at the upper end of the tensioning plate.

[0007] Further, a positioning hole adapted to the end of the screw rod of the adjusting bolt is provided on the top surface of the guiding block at the upper end of the tensioning plate.

[0008] Further, a lower positioning block is fixedly provided on the inner bottom surface of the tensioning cavity, and an upper positioning block is fixedly provided on the bottom surface of the guiding block at the lower end of the tensioning plate. The lower end of the compression spring is sleeved on the lower positioning block, and the upper end of the compression spring is sleeved on the upper positioning block.

[0009] Further, the limiting block is U-shaped. The locking device includes a locking screw and a locking plate. Locking plates are fixedly provided on both the left and right sides of the top of the limiting block. At least one locking hole is provided on the locking plate. An embedding groove adapted to the locking plate is provided at the top end of the column body, and a second threaded hole corresponding to the locking hole is provided on the bottom surface of the embedding groove. The locking screw passes through the locking hole and is threadedly connected to the second threaded hole.

[0010] Further, the installation hole includes a penetrating hole and a clamping hole which are arranged up and down and communicated with each other. The penetrating hole is circular, the clamping hole is U-shaped, and the inner diameter of the penetrating hole is larger than the inner diameter of the clamping hole.

[0011] Further, an installation bottom plate is fixedly provided at the bottom end of the column body, and connection holes are provided at the four corners of the installation bottom plate.

[0012] Further, a top cover is further included, and the top cover is detachably embedded at the opening at the top end of the column body.

[0013] As can be seen from the above description, a column with a connection and tensioning function provided by the present utility model has the following beneficial effects: during the use of the column, there is no need to use a corresponding tensioner. Through the combined use of the tensioning plate and the tensioning driving mechanism, the local winding stroke at both ends of the steel wire rope can be increased, so as to tension multiple steel wire ropes synchronously and play a corresponding connection and tensioning role to form a guardrail. Since there is no need to install a large number of tensioners, the complexity of the overall installation steps can be reduced to a certain extent, and the overall installation is more relaxed and simple.

Specific embodiments

[0024] The present utility model will be further described below through specific embodiments.

[0025] As Figures 1 to 9 shown, a column with a connecting and tensioning function of the present utility model includes a column body 1, a tensioning plate 2 and a tensioning drive mechanism 3.

[0026] An upwardly open cavity 11 is provided in the column body 1, and two symmetrically and longitudinally arranged separators 12 are fixedly provided in the cavity 11. The two separators 12 divide the cavity 11 into a limit cavity 111 and two tensioning cavities 112. The limit cavity 111 is arranged between the two tensioning cavities 112. Preferably, the column body 1 can be made of stainless steel or aluminum.

[0027] A tensioning plate 2 which is longitudinally arranged and can be lifted is provided in each of the two tensioning cavities 112. A plurality of mounting holes 4 which are longitudinally spaced are provided on the left and right side surfaces of the column body 1, the partition plate 12 and the tensioning plate 2. Preferably, the mounting hole 4 includes a penetrating hole 41 and a clamping hole 42 which are arranged up and down and communicate with each other. The penetrating hole 41 is circular, and the clamping hole 42 is U-shaped. The inner diameter of the penetrating hole 41 is larger than the inner diameter of the clamping hole 42. Correspondingly, both ends of a steel wire rope 6 used in cooperation with this column are fixedly crimped with a crimping sleeve 7. The outer diameter of the crimping sleeve 7 is smaller than the inner diameter of the penetrating hole 41 and larger than the inner diameter of the clamping hole 42. In this way, the end of the steel wire rope 6 fixedly crimped with the crimping sleeve 7 can first penetrate through the penetrating holes 41 on the column body 1, the tensioning plate 2 and the partition plate 12 in sequence until the crimping sleeve 7 is located in the limiting cavity 111, and then the steel wire rope 6 is sleeved in the clamping hole 42. At this time, when the tensioning plate 2 tensions the end of the steel wire rope 6, the crimping sleeve 7 can be stably clamped on the inner surface of the partition plate 12 at the clamping hole 42.

[0028] In addition, guide blocks 21 are fixedly provided at the upper and lower ends of the tensioning plate 2. The guide blocks 21 are rectangular parallelepipeds and are adapted to the tensioning cavity 112. The guide blocks 21 are embedded in the tensioning cavity 112 and are in sliding fit with each other up and down. Through the arrangement of the guide blocks 21, the smoothness and smoothness of the tensioning plate 2 during up and down sliding are effectively ensured.

[0029] The tensioning drive mechanism 3 is provided in each of the two tensioning cavities 112. The tensioning drive mechanism 3 is used to drive the tensioning plate 2 to move up and down, so that the mounting holes 4 on the tensioning plate 2 are staggered from the mounting holes 4 on the column 1 and the partition plate 12. The tensioning drive mechanism 3 includes an adjusting bolt 31, a compression spring 32 and a limiting block 33. The limiting block 33 is arranged above the tensioning plate 2 and is detachably installed at the upper opening of the tensioning cavity 112 through a locking device 34. The compression spring 32 is arranged below the tensioning plate 2. The limiting block 33 is provided with a first threaded hole 331 adapted to the adjusting bolt 31. The adjusting bolt 31 is threadedly connected to the first threaded hole 331, and the end of its screw rod abuts against the guiding block 21 at the upper end of the tensioning plate 2. Through the arrangement of the compression spring 32, an upward elastic force can be always applied to the tensioning plate 2. At the same time, with the limiting function of the limiting block 33, the tensioning plate 2 can be in a relatively stable height position. At this time, the mounting holes 4 on the column 1, the mounting holes 4 on the tensioning plate 2 and the mounting holes 4 on the partition plate 12 are in one-to-one correspondence and communicate with each other to facilitate the penetration of the steel wire rope 6. When one end of the steel wire rope 6 fixedly crimped with a crimping sleeve 7 penetrates through the mounting holes 4 on the column 1, the tensioning plate 2 and the partition plate 12 in sequence until the crimping sleeve 7 is in the limiting cavity 111, the adjusting bolt 31 can be rotated by a corresponding tool, so as to push the tensioning plate 2 to move downward, and make the mounting holes 4 on the tensioning plate 2 staggered from the mounting holes 4 on the column 1 and the mounting holes 4 on the partition plate 12. Thus, the local winding stroke of the end of the steel wire rope 6 can be increased, so as to play a corresponding connection and tensioning role on the end of the steel wire rope 6. In addition, the top surface of the guiding block 21 at the upper end of the tensioning plate 2 is provided with a positioning hole 211 adapted to the end of the screw rod of the adjusting bolt 31 to play a corresponding positioning role on the end of the screw rod of the adjusting bolt 31, so as to further ensure the stability of the tensioning process.

[0030] In addition, a lower positioning block 13 is fixedly arranged on the inner bottom surface of the tensioning cavity 112, and an upper positioning block 212 is fixedly arranged on the bottom surface of the guiding block 21 at the lower end of the tensioning plate 2. The lower end of the compression spring 32 is sleeved on the lower positioning block 13, and the upper end of the compression spring 32 is sleeved on the upper positioning block 212. Thus, the installation stability of the compression spring 32 can be further improved.

[0031] Preferably, the limiting block 33 is U-shaped. The locking device 34 includes a locking screw 341 and a locking plate 342. Preferably, the locking screw 341 can be a countersunk screw. The locking plates 342 are fixedly provided on the left and right sides of the top of the limiting block 33. At least one locking hole 3421 is provided on the locking plate 342. Preferably, the number of the locking holes 3421 is two. An embedding groove 14 adapted to the locking plate 342 is provided at the top end of the column 1. A second threaded hole 15 corresponding to the locking hole 3421 is provided on the bottom surface of the embedding groove 14. The locking screw 341 passes through the locking hole 3421 and is threadedly connected to the second threaded hole 15, so as to facilitate the detachable connection between the limiting block 33 and the column 1, and at the same time, the adjusting bolt 31 can be located in the U-shaped limiting block 33 to make the overall structure more compact.

[0032] The bottom end of the column 1 is fixedly provided with a mounting base plate 16. Connecting holes 161 are provided at the four corners of the mounting base plate 16 to facilitate the fixing and installation of the column 1 on the corresponding mounting surface by using corresponding fixing bolts. In addition, the column further includes a top cover 5. The top cover 5 is detachably embedded at the opening at the top end of the column 1 to seal the opening at the top end of the column 1 and improve the overall aesthetics. Correspondingly, a ring-shaped embedding block adapted to the top opening of the limiting cavity 111 is fixedly provided on the lower end surface of the top cover 5. The ring-shaped embedding block is detachably embedded in the top opening of the limiting cavity 111. In addition, the top cover 5 and the column 1 can also be connected by bolts to further lock and fix the top cover 5.

[0033] The using method of a column with a connection and tensioning function according to the present invention is as follows:

[0034] Fix and install two corresponding columns on the corresponding mounting surface;

[0035] Insert one end of a plurality of steel cables 6 into the corresponding column on one side in sequence, and then insert the other ends of the plurality of steel cables 6 into the corresponding column on the other side in sequence. The specific insertion process of one end of the steel cable 6 is as follows: Insert the end of the steel cable 6 fixedly crimped with a crimping sleeve 7 through the insertion holes 41 on the column 1, the tensioning plate 2 and the partition plate 12 in sequence until the crimping sleeve 7 is located in the limiting cavity 111, and then make the steel cable 6 sleeved in the locking hole 42;

[0036] Use the corresponding tool to synchronously rotate the adjusting bolts 31 on the two columns, so as to push the tensioning plate 2 downward, and make the mounting hole 4 of the tensioning plate 2 staggered with the mounting hole 4 on the column 1 and the mounting hole 4 on the partition 12, thereby increasing the local winding stroke of the end of the wire rope 6, so as to play a corresponding connection and tightening role on the end of the wire rope 6. At this time, the crimping sleeve 7 is stably clamped on the inner surface of the partition 12 at the clamping hole 42;

[0037] The top cover 5 is installed at the top opening of the column 1 .

[0038] Therefore, during the use of the column, there is no need to use a corresponding tensioner. Through the coordinated use of the tensioning plate 2 and the tensioning drive mechanism 3, the local winding stroke at both ends of the wire rope 6 can be increased to simultaneously tension multiple wire ropes 6 and play a corresponding connecting and tightening role to form a guardrail. Since there is no need to install a large number of tensioners, the complexity of the overall installation steps can be reduced to a certain extent, and the overall installation is easier and more convenient.

[0039] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made and that such a development effort may be complex and time-consuming, but will be a routine task of design, manufacturing, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0040] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
