Description

Technical Field

[0001] This utility model relates to the field of tents, and in particular to an auxiliary installation structure for tent trusses. Background Technology

[0002] In the construction of tents, the truss serves as the core load-bearing frame (also the tent support). Its installation process is highly dependent on the traction and lifting technology. The typical operation process is as follows: the tent support, which is placed horizontally on the ground, is transported to the erection position. Vertical tension is applied through the traction mechanism to rotate the tent support to a vertical position (usually, one side of the bottom of the tent support is pre-fixed to a rotation fulcrum on the support on the bottom surface), and finally fixed in a vertical support state.

[0003] However, when setting up some large tents, it is usually necessary to use tent support units with a relatively high height. The working height of the traction mechanism needs to reach at least 70%-100% of the total length of the tent support unit in order to effectively apply force. When the height of the tent support unit exceeds 15 meters, the physical limits of conventional traction equipment will not be able to meet the basic traction requirements of the tent support unit. Even if a traction mechanism that meets the height requirements of the tent support unit is designed separately, due to the high height of the tent support unit, the tent support unit is very prone to unexpected swaying when tractioned to an inclined state (such as the asymmetrical effect of wind load on the truss surface). Such disturbances will cause the tent support unit to buckle or twist laterally, or even cause the traction equipment outriggers to lose pressure balance and overturn as a whole, causing inconvenience in setting up the tent support unit. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary installation structure for tent trusses, aiming to solve the technical problem that the tent support is too high and difficult to pull using a traction mechanism.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An auxiliary installation structure for a tent truss includes a traction mechanism and a tent support. The traction mechanism includes a first traction cable and a traction base frame. The traction base frame is located on the ground. The first traction cable is movably located on the top of the traction base frame. One end of the first traction cable is connected to the tent support. The tent support includes a support truss, a movable truss, and a lifting cable. One side of the bottom of the support truss is rotatably connected to a support on the ground. One end of the first traction cable is tied to one side of the support truss. The support truss has a movable cavity inside, which extends through the top of the support truss. The movable truss slides into the movable cavity. A connecting rod is provided at the bottom of the movable truss. One end of the lifting cable passes through the movable cavity, so that the inserted end of the lifting cable is tied to the outside of the connecting rod. A drive unit is detachably connected to one side of the support truss. The other end of the lifting cable is connected to the drive unit, so that the drive unit drives the lifting cable to rewind.

[0007] When the support truss needs to be pulled, the movable truss retracts into the movable cavity of the support truss, while the support truss, as a fixed base, is hinged to the ground support via a pivot point. Because the overall height of the support truss is significantly lower than the overall height of the movable truss extending beyond the support truss when the movable truss is retracted, the first traction cable is movably located at the top of the traction base (usually driven by a conventional drive device for winding). One end of the first traction cable is connected to the support truss, so that under the winding of the drive device, the support truss is pulled to a vertical position by the first traction cable. Therefore, conventionally... The traction device provides sufficient lever arm to allow the supporting truss to rotate around the bottom fulcrum to a vertical position for fixation. Once the supporting truss is fixed, the drive unit drives the lifting cable to retract. Since one end of the lifting cable is tied to the outside of the connecting rod of the movable truss, and the connecting rod is located at the bottom of the movable truss, the connecting rod gradually rises along the movable cavity under the pull of the lifting cable. This causes the movable truss to extend out of the movable cavity, making the movable truss extend out of the cavity, which meets the height requirements of large tents. This simplifies the construction of the support structure for taller tents and ensures the safety of the traction mechanism during traction.

[0008] Furthermore, in this application, the top of the supporting truss is provided with a lifting guide frame, and the lifting guide frame is rotatably connected to a lifting wheel. The lifting wheel is in rolling cooperation with the lifting cable. The interior of the movable cavity is provided with multiple guide frames, and the interior of the guide frames is rotatably connected to guide rollers. The guide rollers are in rolling cooperation with the outer edge of the movable truss.

[0009] When the drive unit retracts the lifting cable, the contact between the lifting cable and the lifting pulley is transformed into rolling contact, which greatly reduces frictional resistance and thus reduces wear on the lifting cable. The guide rollers of multiple guide frames roll in cooperation with the outer edge of the movable truss, thereby guiding the lifting direction of the movable truss and improving the stability of the movable truss during lifting.

[0010] Furthermore, in this application, two limiting plates are provided on the outside of the connecting support rod, and the two limiting plates are separated to form a limiting interval, with one end of the lifting cable located inside the limiting interval.

[0011] When the drive unit retracts the lifting cable, the lifting cable pulls the connecting rod upward, causing the movable truss to rise. Since the lifting cable is constrained within the limit interval, its direction of movement is strictly limited to prevent the binding position of the lifting cable from shifting left or right.

[0012] Furthermore, in this application, the driving unit includes a driving plate, which is detachably connected to one side of the supporting truss. A driving frame is provided on one side of the driving plate, and a driving sheave is rotatably connected inside the driving frame. The other end of the lifting cable is wound around the outside of the driving sheave. A driving motor is provided on one side of the driving frame, and the driving motor drives the driving sheave to rotate.

[0013] Furthermore, in this application, the other side of the drive plate is provided with multiple mounting slots, one side of the support truss is provided with a connecting frame, one side of the connecting frame is provided with multiple connecting protrusions, the multiple connecting protrusions are respectively inserted into the multiple mounting slots, the outer edge of the drive plate is provided with multiple first fixing holes, the multiple first fixing holes are respectively connected to the multiple mounting slots, the inside of the connecting protrusion is provided with a second fixing hole, a fixing bolt is inserted in the first fixing hole, and the fixing bolt is threadedly engaged with the adjacent second fixing hole.

[0014] Furthermore, in this application, the traction mechanism includes a support frame disposed on the top of the traction base frame, a traction plate disposed on one side of the support frame, a traction frame disposed on one side of the traction plate, a traction sheave rotatably connected inside the traction frame, the other end of the first traction cable being wound around the outside of the traction sheave, a traction motor disposed on one side of the traction frame, and the traction motor driving the traction sheave to rotate.

[0015] Furthermore, in this application, the top of the support frame is provided with a first guide wire frame, and the interior of the first guide wire frame is rotatably connected with a first guide wire roller. The first guide wire roller is in rolling cooperation with the first traction cable. A fixing ring is provided on one side of the support truss, and one end of the first traction cable is tied to the fixing ring.

[0016] Furthermore, in this application, a reinforcing rib is provided on the other side of the support frame, one end of which is connected to the top of the traction base frame, and the traction base frame, the reinforcing rib, and the support frame surround each other to form a triangular shape.

[0017] Furthermore, in this application, the top of the movable truss is provided with an auxiliary part, the auxiliary part including a support top plate provided on the top of the movable truss, the top of the support top plate is provided with a limiting top plate, the limiting top plate and the support top plate are separated to form a movable interval, a second traction cable is movably connected inside the movable interval, the other end of the lifting cable is detachably connected to the drive part, when the lifting cable is detached from the drive part, the second traction cable is detachably connected to the drive part, so that the drive part drives the second traction cable to wind.

[0018] Furthermore, in this application, the bottom of the supporting top plate is provided with a supporting base frame, one side of the supporting base frame is provided with a second guide frame, the interior of the second guide frame is rotatably connected with a second guide roller, the top of the supporting top plate is provided with a third guide frame, the interior of the third guide frame is rotatably connected with a third guide roller, the limiting top plate is provided on the top of the third guide frame, the other side of the supporting base frame is provided with a fourth guide frame, the interior of the fourth guide frame is rotatably connected with a fourth guide roller, the interior of the supporting top plate is provided with a first connecting groove and a second connecting groove, the first connecting groove and the second connecting groove communicate with the movable interval, the third guide frame is located between the first connecting groove and the second connecting groove, and the second traction cable passes through the first connecting groove and the second connecting groove, so that the second traction cable rolls in cooperation with the second guide roller, the third guide roller and the fourth guide roller.

[0019] This utility model has the following beneficial effects:

[0020] When the support truss needs to be pulled, the movable truss retracts into the movable cavity of the support truss, while the support truss, as a fixed base, is hinged to the ground support via a pivot point. Because the overall height of the support truss is significantly lower than the overall height of the movable truss extending beyond the support truss when the movable truss is retracted, the first traction cable is movably located at the top of the traction base (usually driven by a conventional drive device for winding). One end of the first traction cable is connected to the support truss, so that under the winding of the drive device, the support truss is pulled to a vertical position by the first traction cable. Therefore, conventionally... The traction device provides sufficient lever arm to allow the supporting truss to rotate around the bottom fulcrum to a vertical position for fixation. Once the supporting truss is fixed, the drive unit drives the lifting cable to retract. Since one end of the lifting cable is tied to the outside of the connecting rod of the movable truss, and the connecting rod is located at the bottom of the movable truss, the connecting rod gradually rises along the movable cavity under the pull of the lifting cable. This causes the movable truss to extend out of the movable cavity, making the movable truss extend out of the cavity, which meets the height requirements of large tents. This simplifies the construction of the support structure for taller tents and ensures the safety of the traction mechanism during traction. Attached Figure Description

[0040] Reference Figures 1-14In some specific embodiments, an auxiliary installation structure for a tent truss includes a traction mechanism 100 and a tent support 300. The traction mechanism 100 includes a first traction cable 150 and a traction base frame 110. The traction base frame 110 is located on the ground, and the first traction cable 150 is movably located on the top of the traction base frame 110. One end of the first traction cable 150 is connected to the tent support 300. The tent support 300 includes a support truss 310, a movable truss 320, and a lifting cable 340. One side of the bottom of the support truss 310 is rotatably connected to a support 500 on the ground. One end of the first traction cable 150 is connected to one side of the support truss 310. The support truss 310 is connected by a fulcrum (e.g., a support point at the top of the truss 310 or other connecting structures). The support truss 310 has a movable cavity 311 inside, which extends through the top of the support truss 310. The movable truss 320 slides into the movable cavity 311. The bottom of the movable truss 320 is provided with a connecting rod 321. One end of the lifting cable 340 passes through the movable cavity 311, so that the end of the lifting cable 340 is tied to the outside of the connecting rod 321. A drive unit 200 is detachably connected to one side of the support truss 310. The other end of the lifting cable 340 is connected to the drive unit 200, so that the drive unit 200 drives the lifting cable 340 to rewind.

[0041] Through the above technical solution, when the support truss 310 needs to be pulled, the movable truss 320 retracts into the movable cavity 311 of the support truss 310. The support truss 310, as a fixed base, is hinged to the support 500 on the ground through a rotating fulcrum. Since the overall height of the support truss 310 is significantly lower than the overall height of the movable truss 320 extending out of the support truss 310 when the movable truss 320 is in the retracted state, the first traction cable 150 is movably located at the top of the traction base frame 110 (usually driven by the existing drive device in the traction mechanism 100 to wind up the first traction cable 150). One end of the first traction cable 150 is connected to the support truss 310, so that the support truss 310 is pulled vertically by the first traction cable 150 under the winding of the drive device. Therefore, conventional traction equipment can provide sufficient lever arm, allowing the support truss 310 to rotate around the bottom fulcrum to a vertical position for fixation. After the support truss 310 is fixed, the drive unit 200 drives the lifting cable 340 to rewind. Since one end of the lifting cable 340 is tied to the outside of the connecting rod 321 of the movable truss 320, and the connecting rod 321 is located at the bottom of the movable truss 320, the connecting rod 321 gradually rises along the movable cavity 311 under the pull of the lifting cable 340. Thus, the movable truss 320 extends out of the movable cavity 311 through the connecting rod 321, so that the movable truss 320 is in an extended state, which meets the height requirements of large tents, thereby simplifying the construction of the tall tent support unit 300 and ensuring the safety of the traction mechanism 100 during traction.

[0042] In addition, to ensure the stability of the movable truss 320 during lifting and lowering, there can be two connecting rods 321, which are symmetrically arranged at the bottom of the movable truss 320. Each movable truss 320 is externally bound with a lifting cable 340, and there are also two drive units 200, which are symmetrically arranged on both sides of the supporting truss 310 and drive the adjacent lifting cables 340 respectively. This makes the movable truss 320 form a balanced couple under the force of the two lifting cables 340, ensuring the stability of the movable truss 320 during lifting and lowering. Furthermore, if any drive unit 200 fails, the other drive unit 200 can still ensure the lifting and lowering of the movable truss 320. The first traction cable 150 can be wound up by the drive device or by a manual crank.

[0043] It should be noted that the external binding of the lifting cable 340 and the connecting rod 321 of the movable truss 320 is only to enable the lifting of the movable truss 320. When the movable truss 320 extends out of the movable cavity 311 or is raised to the required height, the movable truss 320 will be connected to the movable cavity 311 by multiple bolts. In addition, multiple steel cables need to be installed on the side of the movable truss 320, with one end of the steel cable fixed to the bottom surface, so as to ensure the stability of the movable truss 320 during use.

[0044] Reference Figures 9-14 In some specific embodiments, the top of the supporting truss 310 is provided with a lifting guide frame 350, and the lifting guide frame 350 is rotatably connected to a lifting wheel 351. The lifting wheel 351 is in rolling cooperation with the lifting cable 340. The interior of the movable cavity 311 is provided with multiple guide frames 312, and the interior of the guide frame 312 is rotatably connected to a guide roller 313. The guide roller 313 is in rolling cooperation with the outer edge of the movable truss 320.

[0045] Through the above technical solution, when the drive unit 200 winds up the lifting cable 340, the contact between the lifting cable 340 and the lifting pulley 351 is transformed into rolling contact, which greatly reduces the frictional resistance and thus reduces the wear of the lifting cable 340; through the rolling cooperation between the guide rollers 313 of the multiple guide frames 312 and the outer edge of the movable truss 320, the lifting direction of the movable truss 320 is guided, thereby improving the stability of the movable truss 320 during lifting.

[0046] Reference Figures 9-14 In some specific embodiments, two limiting plates 322 are provided on the outside of the connecting rod 321, and the two limiting plates 322 are separated to form a limiting interval 323. One end of the lifting cable 340 is located inside the limiting interval 323.

[0047] With the above technical solution, when the drive unit 200 retracts the lifting cable 340, the lifting cable 340 pulls the connecting support rod 321 upward, causing the movable truss 320 to rise. Since the lifting cable 340 is constrained within the limit interval 323, its movement direction is strictly limited to prevent the binding position of the lifting cable 340 from shifting to the left or right.

[0048] Reference Figures 13-14 In some specific embodiments, the drive unit 200 includes a drive plate 210, which is detachably connected to one side of the support truss 310. A drive frame 211 is provided on one side of the drive plate 210, and a drive wheel 212 is rotatably connected inside the drive frame 211. The other end of the lifting cable 340 is wound around the outside of the drive wheel 212. A drive motor 213 is provided on one side of the drive frame 211, and the drive motor 213 drives the drive wheel 212 to rotate.

[0049] With the above technical solution, when the movable truss 320 needs to be raised, the drive motor 213 drives the drive wheel 212 to rotate, and the other end of the lifting cable 340 is wound around the wheel. As the drive wheel 212 rotates, the lifting cable 340 is wound up, thereby controlling the raising of the movable truss 320.

[0050] Reference Figures 13-14 In some specific embodiments, the other side of the drive plate 210 is provided with a plurality of mounting slots 216, the support truss 310 is provided with a connecting frame 330 on one side, and a plurality of connecting protrusions 331 are provided on one side of the connecting frame 330. The plurality of connecting protrusions 331 are respectively inserted into the plurality of mounting slots 216. The outer edge of the drive plate 210 is provided with a plurality of first fixing holes 214, and the plurality of first fixing holes 214 are respectively connected to the plurality of mounting slots 216. The interior of the connecting protrusions 331 is provided with a second fixing hole 332. A fixing bolt 215 passes through the first fixing hole 214 and is threadedly engaged with the adjacent second fixing hole 332.

[0051] Through the above technical solution, the drive unit 200 and the support truss 310 are detachably connected. In case of failure, the entire drive module can be directly replaced, reducing downtime. Furthermore, after the movable truss 320 is raised and fixed, the drive unit 200 can be disassembled to a new support truss 310, facilitating the multiple uses of the drive unit 200. When the drive unit 200 is installed, multiple connecting protrusions 331 are respectively inserted into multiple mounting slots 216, and the fixing bolts 215 pass through the first fixing hole 214 and are threaded into the adjacent second fixing hole 332, thereby facilitating the fixing of the drive plate 210 of the drive unit 200 to one side of the support truss 310.

[0052] Reference Figures 1-14 In some specific embodiments, the traction mechanism 100 includes a support frame 120 disposed on the top of the traction base frame 110, a traction plate 140 disposed on one side of the support frame 120, a traction frame 160 disposed on one side of the traction plate 140, a traction wheel 161 rotatably connected inside the traction frame 160, the other end of the first traction cable 150 being wound around the outside of the traction wheel 161, and a traction motor 162 disposed on one side of the traction frame 160, the traction motor 162 driving the traction wheel 161 to rotate.

[0053] With the above technical solution, after the traction motor 162 starts, the traction motor 162 drives the traction wheel 161 to rotate. Since the other end of the first traction cable 150 is wrapped around the outside of the traction wheel 161, and one end of the first traction cable 150 is connected to the tent support part 300, the first traction cable 150 will be wound up as the traction wheel 161 rotates, thereby driving the tent support part 300 to be pulled.

[0054] Reference Figures 1-10 In some specific embodiments, the top of the support frame 120 is provided with a first guide frame 130, and the first guide roller 131 is rotatably connected inside the first guide frame 130. The first guide roller 131 is in rolling cooperation with the first traction cable 150. A fixing ring 314 is provided on one side of the support truss 310, and one end of the first traction cable 150 is tied to the fixing ring 314.

[0055] With the above technical solution, when the first traction cable 150 is wound up as the traction sheave 161 rotates, the first guide roller 131 and the first traction cable 150 roll together, and the sliding friction is changed into rolling friction, which greatly reduces the frictional resistance, thereby reducing the wear of the first traction cable 150 and reducing the traction resistance of the first traction cable 150.

[0056] Reference Figures 1-2 In some specific embodiments, a reinforcing rib 121 is provided on the other side of the support frame 120. One end of the reinforcing rib 121 is connected to the top of the traction base frame 110. The traction base frame 110, the reinforcing rib 121 and the support frame 120 surround each other to form a triangular shape.

[0057] With the above technical solution, when the traction motor 162 applies tension through the first traction cable 150, the support frame 120 will bear bending moment. The reinforcing rib 121 converts part of the bending moment into axial pressure, which is transmitted obliquely to the traction base frame 110, significantly reducing the stress concentration at the root of the support frame 120 and preventing the support frame 120 from twisting or tilting.

[0058] Reference Figures 1-10 In some specific embodiments, the top of the movable truss 320 is provided with an auxiliary part 400. The auxiliary part 400 includes a support top plate 420 provided on the top of the movable truss 320. The top of the support top plate 420 is provided with a limiting top plate 450. The limiting top plate 450 and the support top plate 420 are separated to form a movable interval 411. A second traction cable 410 is movably connected inside the movable interval 411. The other end of the lifting cable 340 is detachably connected to the drive part 200. When the lifting cable 340 is detached from the drive part 200, the second traction cable 410 is detachably connected to the drive part 200, so that the drive part 200 drives the second traction cable 410 to pull.

[0059] Through the above technical solution, when setting up a large tent, multiple tent support sections 300 are usually required, and these multiple tent support sections 300 are spaced apart. When any support truss 310 is pulled to a vertical position, since the other end of the lifting cable 340 is detachably connected to the drive unit 200, and the second traction cable 410 is detachably connected to the drive unit 200, the drive unit 200 is first connected to the second traction cable 410, and one end of the second traction cable 410 is used to tie to the support truss 310 of the adjacent tent support section 300. The support truss 310 of the tent support section 300 (which has not yet been pulled) is driven by the drive section 200 to wind up the second traction cable 410, so that the second traction cable 410 pulls the adjacent support truss 310. Therefore, there is no need to add an additional traction mechanism 100. Only one drive section 200 is needed to complete the multi-level traction task, reducing equipment costs and site occupation. After the adjacent support truss 310 is successfully pulled, the lifting cable 340 is reconnected to the drive section 200, thereby restoring the lifting function of the movable truss 320.

[0060] It should be noted that the lifting cable 340 and the second traction cable 410 can be connected to the drive unit 200 through a detachable structure of the prior art, or they can be detachably connected by winding or unwinding the roller of the drive unit 200.

[0061] Reference Figures 1-7 In some specific embodiments, a support base 430 is provided at the bottom of the support top plate 420, a second guide rail 431 is provided on one side of the support base 430, and a second guide roller 433 is rotatably connected inside the second guide rail 431. A third guide rail 440 is provided at the top of the support top plate 420, and a third guide roller 441 is rotatably connected inside the third guide rail 440. A limiting top plate 450 is provided on the top of the third guide rail 440. A fourth guide rail 432 is provided on the other side of the support base 430. The internal rotatable connection is a fourth guide roller 434. The support top plate 420 has a first connecting groove 421 and a second connecting groove 422 inside. The first connecting groove 421 and the second connecting groove 422 are connected to the movable interval 411. The third guide frame 440 is located between the first connecting groove 421 and the second connecting groove 422. The second traction cable 410 passes through the first connecting groove 421 and the second connecting groove 422, so that the second traction cable 410 rolls in cooperation with the second guide roller 433, the third guide roller 441 and the fourth guide roller 434.

[0062] With the above technical solution, when the drive unit 200 drives the second traction cable 410 to wind up, the second traction cable 410 rolls in cooperation with the second guide roller 433, the third guide roller 441 and the fourth guide roller 434, which greatly reduces the frictional resistance, thereby reducing the wear of the second traction cable 410 and reducing the traction resistance of the second traction cable 410.
