Description

Technical Field

[0001] The present invention relates to the technical field of gymnasium construction, and in particular to a lifting and sliding system and method for a gymnasium steel structure roof. Background Art

[0002] A gymnasium is a building used for indoor sports competitions, physical exercise or concerts. Gymnasiums can be divided into two categories: competition halls and practice halls according to their use; they can be divided into basketball halls, ice hockey halls, track and field halls, etc. according to the sports; they can be divided into large, medium and small according to their size, and are generally divided according to the number of spectator seats.

[0003] For example, the utility model publication with announcement number CN116623968A discloses a steel structure roof lifting and sliding system, in which the tops of multiple support frames are fixedly connected to the same channel steel, and the tops of two sliding plates on one side of the channel steel are fixedly connected to multiple first connecting frames, the inner wall of the first connecting frame passes through the outer wall fixed sleeve of the first rotating shaft that is rotatably connected to be provided with a wire take-up roller, the outer wall of the wire take-up roller is fixedly connected and wound with a wire rope, and the other end of the wire rope is connected to the roof; the top of the channel steel is fixedly connected to a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to one end of the sliding plate, so as to drive the sliding plate to move laterally; a transmission structure is arranged on one side of the first connecting frame, so as to simultaneously drive multiple first rotating shafts to rotate, so as to make the lifting and lowering stable; an anti-falling mechanism is arranged on the top of the first connecting frame, so as to prevent the roof from falling when the wire rope breaks; a stabilizing mechanism is arranged under the sliding plate, so as to make the sliding plate more stable when moving; the synchronous lifting and sliding process of the entire steel structure roof is smoother and safer.

[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing steel structure roof lifting and sliding systems use a driving mechanism to drive the steel cable to pull the roof to move, so that its lifting and sliding are stable, but most of the lifting and sliding systems are unable to move the roof to an area outside their own range for installation during use, so that subsequent staff need to adjust the position of the mobile lifting and sliding system multiple times when using the device to install multiple groups of roofs, thereby reducing the practicality of the equipment.

[0023] A method for implementing a lifting and sliding system for a gymnasium steel structure roof comprises:

[0024] Step 1. Preparation

[0025] By rotating the two sets of rotating rods outward, the opposite sides of the two sets of supporting blocks are both abutted against the ground, and then the two sets of positioning blocks are pushed to move by starting the two sets of electric telescopic rods, and the upper surfaces of the two sets of positioning blocks are respectively abutted against the adjacent sides of the two sets of I-beam pillars, and the fixing mechanism fixes the base at the position between the two sets of I-beam pillars for positioning;

[0026] When the upper surfaces of the subsequent two sets of positioning blocks abut between two adjacent sets of I-beam pillars in the gymnasium, by pushing the two sets of L-shaped limit rods to move, the ends of the two sets of L-shaped limit rods away from the adjacent set of rotating rods are respectively inserted into the grooves of the two sets of U-shaped fixing blocks, and the two sets of limit mechanisms limit the rotational positions of the two sets of rotating rods during use;

[0027] Step 2: Clamp the roof

[0028] The roof is hoisted by hoisting equipment and temporarily placed on the top plate. Each set of roof installation operation uses at least two sets of front and rear bases;

[0029] By starting the second motor to drive the bidirectional threaded rod to trigger the two sets of limit plates to move, the adjacent sides of the two sets of limit plates are respectively abutted against the left and right sides of the roof on the top plate, so that the positioning mechanism limits the moving position of the roof at the upper end of the top plate;

[0030] By adjusting the operating handles of the worm screws on the sides of the two sets of connecting sleeves, the top plate rotates around the arc surface at the top of the connecting sleeve, and the angle of the roof is adjusted to be able to pass through the gap of the top keel. During the adjustment process, the front and rear drive motors on the base at the lower end of the roof adjust the bottom plate to move backward to adapt to the change in the distance between the two sets of bottom plates caused by the change in the angle of the roof;

[0031] Step 3: Lift the roof

[0032] By starting the hydraulic cylinder to push the connecting sleeve to drive the top plate and the roof through the gap of the top keel, the handle moves to the area where the height of the lower end of the roof is greater than the installation height;

[0033] Step 4: Lay the roof flat

[0034] Adjust the operating handles of the worms on the sides of the two sets of connecting sleeves in reverse order, and the top plate rotates the handle around the arc surface on the top of the connecting sleeve to reset;

[0035] During the adjustment process, the front and rear drive motors on the base at the lower end of the roof adjust the bottom plate to move forward to adapt to the change in the distance between the two sets of bottom plates caused by the change in the angle of the roof, until the roof is adjusted to a parallel keel state;

[0036] By starting the hydraulic cylinder, the connecting sleeve drives the top plate to slowly drop onto the keel;

[0037] Steps, sliding roof

[0038] Then, the motor is started to drive the threaded rod to trigger the slider to drive the fixing plate to slide on the upper end of the base, so that the subsequent fixing plate drives the roof cover at the upper end of the top plate to slide to the installation position during the sliding process;

[0039] After the installation is completed, the two sets of limit plates are triggered by starting the second motor to drive the bidirectional threaded rod to move in the opposite direction and detach from the roof;

[0040] Finally, the hydraulic cylinder is started again to push the connecting sleeve to drive the top plate to return to the initial height.

[0041] The beneficial effects of the present invention are as follows:

[0042] 1. The present invention starts the hydraulic cylinder to push the connecting sleeve to drive the top plate and the roof to move to the area of ​​the roof installation height, and then starts the motor to drive the threaded rod to trigger the slider to drive the fixed plate to slide on the upper end of the base, so that the subsequent fixed plate drives the roof at the upper end of the top plate to slide to the installation position during the sliding process, so that the device can install and position multiple groups of roofs in multiple areas without adjusting the position of the mobile base during use, thereby improving the lifting and driving range of the device, thereby reducing the labor consumed by subsequent staff when using the device to install multiple groups of roofs, thereby improving the practicality of the device.

[0043] 2. The present invention rotates the two sets of rotating rods to make the opposite sides of the two sets of supporting blocks abut against the ground, and then starts the two sets of electric telescopic rods to push the two sets of positioning blocks to move, so that the upper surfaces of the two sets of positioning blocks abut against the adjacent sides of the two sets of I-beam pillars, respectively, so that the fixing mechanism positions the position of the base between the two sets of I-beam pillars, thereby avoiding the base from moving during use as much as possible, thereby improving the stability of the device during use; the two sets of positioning blocks synchronously drive the four sets of sliding rods to slide inside the two sets of through holes of the two sets of rotating rods during the adjustment and movement process, so that the four sets of sliding rods limit the moving paths of the two sets of positioning blocks, thereby avoiding the subsequent positions of the two sets of positioning blocks from being offset as much as possible to cause the two sets of electric telescopic rods to bend, thereby improving the service life of the two sets of electric telescopic rods.

[0044] 3. The present invention realizes the front and rear position adjustment of the bottom plate relative to the base through the front and rear adjustment mechanism. In the specific implementation, it is often encountered that some top keel gaps cannot directly meet the jacking problem of the roof. Therefore, the inventor makes a specific design, and uses the rotation of the worm on the connecting sleeve to drive the worm gear surface on the ear plate at the bottom of the top plate to rotate, so as to adjust the angle of the top plate. In implementation, two groups of bases are used to install the roof. The roof is first tilted at a certain angle to meet the requirement of passing through the top keel gap. During the process, the front and rear drive motors move the bottom plate forward and backward to adjust the spacing between the two groups of bottom plates. When the roof passes through the keel and the height of the lower end position is greater than the installation surface, the position parallel to the installation surface is adjusted again, thereby being able to solve the roof installation problem under complex conditions.

The grooves are arranged front and back, and a front-to-back adjustment screw 702 is rotatably installed in the groove. A front-to-back adjustment nut 703 is installed on the front-to-back adjustment screw 702. The front-to-back adjustment nut 703 is slidably fitted in the groove, and the front-to-back adjustment nut 703 is installed at the bottom of the driving mechanism 2. The front-to-back drive motor 701 drives the front-to-back adjustment nut 703 to move forward and backward, thereby adjusting the front-to-back position of the roof.

[0062] like Figure 1 , Figure 2 and Figure 4As shown, the driving mechanism 2 includes a base plate 201, which is mounted on the upper surface of the front and rear adjusting nuts 703. A card slot is provided on the upper surface of the base plate 201, and through holes are provided on the inner walls on both sides of the card slot. Threaded rods 206 are rotatably connected inside the two groups of through holes. A motor 205 is provided on the right side of the base plate 201, and the output shaft of the motor 205 is mounted on the right side of the threaded rod 206. A slider 209 is connected to the outer thread of the threaded rod 206, and the slider 209 is slidably connected to Inside the slot of the base plate 201, a fixed plate 202 is installed on the upper surface of the slider 209, a fixed sleeve 203 is provided on the upper surface of the fixed plate 202, a connecting sleeve 204 is slidably connected to the inner wall of the fixed sleeve 203, a hydraulic cylinder 208 is provided at the bottom of the inner wall of the fixed sleeve 203, an output end of the hydraulic cylinder 208 is installed on the top of the inner wall of the connecting sleeve 204, a top plate 207 is provided on the upper surface of the connecting sleeve 204, and a roof is placed on the upper surface of the top plate 207.

[0063] Specifically, when the roof is placed on the upper surface of the top plate 207, the hydraulic cylinder 208 is started to push the connecting sleeve 204 to drive the top plate 207 and the roof to move to the area of ​​the roof installation height, and then the motor 205 is started to drive the threaded rod 206 to trigger the slider 209 to drive the fixed plate 202 to slide on the upper end of the base 1, so that the subsequent fixed plate 202 drives the roof on the upper end of the top plate 207 to slide to the installation position during the sliding process, so that the device can install and position multiple groups of roofs in multiple areas without adjusting the position of the mobile base 1 during use, thereby improving the lifting and driving range of the device, thereby reducing the labor consumed by subsequent staff when using the device to install multiple groups of roofs, thereby improving the practicality of the device.

[0064] like Figure 1 and Figure 2 As shown, the positioning mechanism 3 includes a motor 2 301 and a bidirectional threaded rod 302, a slot is provided on the upper surface of the top plate 207, through holes are provided on the inner walls on the left and right sides of the slot of the bidirectional threaded rod 302, the bidirectional threaded rod 302 is rotatably connected inside the two groups of through holes, the motor 2 301 is installed on the side of the top plate 207 close to the motor 1 205, the output shaft of the motor 2 301 is installed on one end of the bidirectional threaded rod 302 close to the motor 1 205, the external threads of the bidirectional threaded rod 302 are connected with two groups of limit plates 303, and an inclined plate 304 is provided on the adjacent side of the two groups of limit plates 303.

[0065] Specifically, by starting the second motor 301 to drive the bidirectional threaded rod 302 to trigger the two groups of limit plates 303 to move, the adjacent sides of the two groups of limit plates 303 are respectively abutted against the left and right sides of the upper end of the roof of the top plate 207, so that the positioning mechanism 3 limits the moving position of the upper end of the roof of the top plate 207, thereby trying to avoid the subsequent top plate 207 from falling from the upper end of the top plate 207 when the roof is lifted and slid, thereby improving the safety of the device when lifting and sliding the roof; when the roof is set as an inclined plane, the position of the two groups of inclined plates 304 is set between the two groups of limit plates 303, so that the adjacent side inclined surfaces of the two groups of inclined plates 304 are abutted against the inclined surfaces on the left and right sides of the roof, thereby allowing the two groups of inclined plates 304 to increase the contact area between the positioning mechanism 3 and the roof, thereby trying to avoid the subsequent positioning mechanism 3 from being unable to position the roof set as an inclined plane during use.

[0066] like Figure 1 and Figure 2 As shown, the fixing mechanism 4 includes two groups of rotating rods 401, and the two groups of rotating rods 401 are respectively rotatably connected to the inside of the two groups of positioning slots of the base 1, and the two groups of rotating rods 401 are respectively provided with support blocks 402 on the opposite sides, and the upper surfaces of the two groups of rotating rods 401 are provided with slots, and the inner wall bottoms of the two groups of slots are installed with electric telescopic rods 403, and the output ends of the two groups of electric telescopic rods 403 are installed with positioning blocks 405, and the lower surfaces of the two groups of positioning blocks 405 are provided with two groups of sliding rods 404, and the upper surfaces of the two groups of rotating rods 401 are provided with through holes, and the two adjacent groups of sliding rods 404 are respectively slidably connected to the inside of the two groups of through holes of the adjacent group of rotating rods 401;

[0067] Specifically, when the subsequent base 1 is placed between two adjacent groups of I-beam pillars in the gymnasium, the two groups of rotating rods 401 are rotated to make the opposite sides of the two groups of support blocks 402 abut against the ground, and then the two groups of electric telescopic rods 403 are started to push the two groups of positioning blocks 405 to move, and the upper surfaces of the two groups of positioning blocks 405 are respectively abutted against the adjacent sides of the two groups of I-beam pillars, so that the fixing mechanism 4 can position the position of the base 1 between the two groups of I-beam pillars, thereby avoiding the base 1 from moving during use as much as possible, thereby improving the stability of the device during use;

[0068] During the adjustment and movement process, the two groups of positioning blocks 405 synchronously drive the four groups of sliding rods 404 to slide inside the two groups of through holes of the two groups of rotating rods 401, so that the four groups of sliding rods 404 limit the movement paths of the two groups of positioning blocks 405, thereby avoiding as much as possible the subsequent positions of the two groups of positioning blocks 405 being offset and causing the two groups of electric telescopic rods 403 to bend, thereby increasing the service life of the two groups of electric telescopic rods 403.

[0069] like Figure 5 , 6As shown, the two groups of limiting mechanisms 6 include a U-shaped fixing block 601 and an L-shaped limiting rod 602. The two groups of U-shaped fixing blocks 601 are installed on the upper surface of the base 1. The adjacent sides of the two groups of rotating rods 401 are provided with grooves. The two groups of L-shaped limiting rods 602 are respectively slidably connected to the grooves of the two groups of rotating rods 401. The positions of the grooves inside the two groups of U-shaped fixing blocks 601 are respectively located on the moving paths of the two groups of L-shaped limiting rods 602 away from one end of the adjacent group of rotating rods 401.

[0070] Specifically, when the upper surfaces of the subsequent two groups of positioning blocks 405 abut between two adjacent groups of I-beam pillars in the gymnasium, the two groups of L-shaped limit rods 602 are pushed to move, and the ends of the two groups of L-shaped limit rods 602 away from the adjacent group of rotating rods 401 are respectively inserted into the grooves of the two groups of U-shaped fixing blocks 601, so that the two groups of limiting mechanisms 6 limit the rotation position of the two groups of rotating rods 401 during use, thereby avoiding the subsequent two groups of rotating rods 401 from rotating during use as much as possible, thereby improving the stability of the fixing mechanism 4 during use.

[0071] like Figure 1 and Figure 2 As shown, the position of the top plate 207 is located at the upper end of the two groups of positioning blocks 405; specifically, when the device is subsequently transported and moved, the two groups of rotating rods 401 are rotated to rotate the position of the upper surfaces of the two groups of rotating rods 401 to the lower end of the top plate 207, and then the two groups of electric telescopic rods 403 are started to push the two groups of positioning blocks 405 to move, and the upper surfaces of the two groups of positioning blocks 405 are abutted against the lower surface of the top plate 207, so that the subsequent top plate 207 restricts the position of the two groups of rotating rods 401 during the transportation and movement process, thereby minimizing the subsequent two groups of rotating rods 401 from unfolding during the transportation and movement of the device, causing the two groups of rotating rods 401 to block the staff from carrying the equipment normally.

[0072] like Figure 1 As shown, the support mechanism 5 includes a support plate 501, which is mounted on the front of the fixed sleeve 203. The lower surface of the support plate 501 is provided with an arc-shaped positioning plate 502, and the back of the arc-shaped positioning plate 502 is mounted on the front of the fixed sleeve 203;

[0073] Specifically, by setting the support plate 501 in the middle area between the top plate 207 and the base 1, the subsequent workers can first move the heavy roof to the upper surface of the support plate 501 and then move it to the upper surface of the top plate 207 when moving the heavy roof, so that the subsequent workers have a buffer time when moving the heavy roof, thereby improving the safety of the subsequent workers when moving the heavy roof to the upper surface of the top plate 207, thereby improving the practicality of the device;

[0074] By installing the back side of the arc-shaped positioning plate 502 on the front side of the fixed sleeve 203, the contact area between the support plate 501 and the front side of the connecting sleeve 204 is increased through the arc-shaped positioning plate 502, so that the arc-shaped positioning plate 502 supports the support plate 501, thereby minimizing the bending of the support plate 501 when the subsequent roof is placed on the upper surface of the support plate 501; the installation area of ​​the support plate 501 is relatively low, so that the subsequent staff can climb to the upper end of the top plate 207 through the support plate 501 during the inspection and maintenance of the positioning mechanism 3, so that the subsequent staff does not need to take climbing tools during the inspection and maintenance of the positioning mechanism 3, thereby reducing the labor and time consumed by the subsequent staff in inspecting and maintaining the positioning mechanism 3.

[0075] like Figure 1 , Figure 3 , Figure 4 As shown, the top of the connecting sleeve 204 is provided with an arc surface, and the bottom surface of the top plate 207 is provided with an adapting surface adapted to the arc surface;

[0076] An ear plate 211 is provided at the bottom of the top plate 207, and the ear plate 211 is rotatably installed on the top of the connecting sleeve 204. The side of the connecting sleeve 204 is provided with a worm 210 installed front and back. The bottom surface of the ear plate 211 is provided with a worm wheel surface adapted to the worm 210, and an operating handle is provided at one end of the worm 210.

[0077] A method for implementing a lifting and sliding system for a gymnasium steel structure roof comprises:

[0079] By rotating the two sets of rotating rods 401 outward, the opposite sides of the two sets of supporting blocks 402 are both abutted against the ground, and then the two sets of electric telescopic rods 403 are started to push the two sets of positioning blocks 405 to move, and the upper surfaces of the two sets of positioning blocks 405 are respectively abutted against the adjacent sides of the two sets of I-beam pillars, and the fixing mechanism 4 fixes the base 1 at the position between the two sets of I-beam pillars for positioning;

[0080] When the upper surfaces of the subsequent two groups of positioning blocks 405 abut between two adjacent groups of I-beam pillars in the gymnasium, by pushing the two groups of L-shaped limiting rods 602 to move, the ends of the two groups of L-shaped limiting rods 602 away from the adjacent group of rotating rods 401 are respectively inserted into the grooves of the two groups of U-shaped fixing blocks 601, and the two groups of limiting mechanisms 6 limit the rotational positions of the two groups of rotating rods 401 during use;

[0081] Step 2: Clamp the roof

[0082] The roof is hoisted by hoisting equipment and temporarily placed on the top plate 207. The installation operation of each set of roofs uses at least two sets of front and rear bases 1;

[0083] By starting the second motor 301 to drive the bidirectional threaded rod 302 to trigger the two sets of limit plates 303 to move, the adjacent sides of the two sets of limit plates 303 are respectively abutted against the left and right sides of the roof on the top plate 207, so that the positioning mechanism 3 limits the moving position of the roof on the top plate 207;

[0084] By adjusting the operating handles of the worm screws 210 on the sides of the two sets of connecting sleeves 204, the top plate 207 rotates around the arc surface at the top of the connecting sleeve 204, and the angle of the roof is adjusted to be able to pass through the gap of the top keel. During the adjustment process, the front and rear drive motors (701) on the base 1 at the lower end of the roof adjust the bottom plate 201 to move backward to adapt to the change in the distance between the two sets of bottom plates 201 caused by the change in the angle of the roof;

[0085] Step 3: Lift the roof

[0086] By starting the hydraulic cylinder 208 to push the connecting sleeve 204 to drive the top plate 207 and the roof to pass through the gap of the top keel, the handle moves to the area at the lower end of the roof where the height is greater than the installation height;

[0087] Step 4: Lay the roof flat

[0088] Adjust the operating handles of the worm screws 210 on the sides of the two sets of connecting sleeves 204 in reverse, and the top plate 207 rotates around the arc surface on the top of the connecting sleeve 204 to reset;

[0089] During the adjustment process, the front and rear drive motors (701) on the base 1 at the lower end of the roof adjust the bottom plate 201 to move forward to adapt to the change in the distance between the two groups of bottom plates 201 caused by the change in the angle of the roof, until the roof is adjusted to a parallel keel state;

[0090] By starting the hydraulic cylinder 208, the connecting sleeve 204 drives the top plate 207 to slowly drop onto the keel;

[0091] Step 5: Slide the roof

[0092] Then, the motor 1 205 is started to drive the threaded rod 206 to trigger the slider 209 to drive the fixed plate 202 to slide on the upper end of the base 1, so that the fixed plate 202 drives the upper end of the top plate 207 to slide to the installation position during the sliding process;

[0093] After the installation is completed, the two sets of limit plates 303 are triggered by starting the second motor 301 to drive the bidirectional threaded rod 302 to move in the opposite direction and detach from the roof;

[0094] Finally, the hydraulic cylinder 208 is started again to push the connecting sleeve 204 to drive the top plate 207 to return to the initial height.
