Description

Technical Field

[0001] The utility model relates to the technical field of concrete component manufacturing, in particular to a telescopic steaming shed. Background Art

[0002] In recent years, the factory production of prefabricated components has achieved rapid development. In the fields of cast-in-place construction such as transportation and construction, the construction has gradually shifted to prefabricated component assembly construction, which not only improves work efficiency but also effectively ensures quality. When there are technical difficulties in winter construction or for concrete projects with high early strength requirements, steam curing sheds are required to cure the freshly poured concrete. Steam is a good heat carrier. It releases a lot of heat when condensed and has a high heat release coefficient. It can heat and harden the concrete at a higher temperature, and it can also supply a certain amount of water to prevent the concrete from drying out and dehydrating on the surface due to excessive evaporation of water.

[0003] After the prefabricated beams are completed, the beams and slabs need to be steam-cured. The prefabricated beam yard casts new beams and slabs every day. If tarpaulins are used to cover them manually, multiple workers will need to work continuously to cover them with the tarpaulins. This is a huge waste of labor, inefficient, and easy to damage the tarpaulins. The turnover rate is low, materials are wasted, costs are increased, and it is difficult to ensure the quality of maintenance. At the same time, if the beams and slabs are not covered in time after casting, the newly poured concrete will be frozen, affecting the construction quality. Utility Model Content

DETAILED DESCRIPTION

[0039] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0040] like Figure 1-Figure 7As shown, a telescopic steaming and curing shed can perform steam curing on the precast beam concrete after the pouring construction is completed by splicing adjacent thermal insulation panels 3 and dropping the side thermal insulation protective cloth 10. Workers do not need to work intermittently, thereby improving construction efficiency and reducing labor waste. Specifically, it includes two shells 1 spaced apart from each other, and a driving rod 5 extending in the left and right directions is provided inside the shell 1. A first driving device 6 (the first driving device 6 is a first driving self-locking motor) is fixedly provided at one end of the driving rod 5, and the other end of the driving rod 5 is rotatably provided on the inner side wall of the shell 1. A plurality of movable blocks 7 spaced apart from each other are sleeved on the driving rod 5, and a cavity 8 is provided inside the movable block 7. After the first driving device 6 is started, the output shaft of the first driving device 6 can drive the driving rod 5 to rotate.

[0041] A plurality of first worm gears 11 spaced apart from each other are slidably mounted on the driving rod 5. When the driving rod 5 rotates, the first worm gears 11 can be driven to rotate. The first worm gears 11 are respectively connected to the driving lifting mechanism 9 and the driving rotating mechanism 2 for transmission. When the first worm gears 11 rotate, the first worm gears 11 can be driven to rotate. The first worm gears 11 are located in the cavity 8.

[0042] By setting the driving rotating mechanism 2, the driving rod 5 can drive the driving rotating mechanism 2 to rotate when it rotates, so that the thermal insulation panels 3 can be spliced ​​together to form a protective top plate after rotation. Specifically, a driving rotating mechanism 2 is provided on the upper side of the interior of the cavity 8, and the thermal insulation panels 3 are transmitted between the two driving rotating mechanisms 2 on the same side of the front and rear. In the initial state, the thermal insulation panels 3 are all in a vertical state and moved to one side. When in use, the thermal insulation panels 3 can be evenly moved first, and then the thermal insulation panels 3 are turned over and spliced. The thermal insulation panels 3 are provided with a steam injection head, which can spray steam inside for maintenance. The driving rotating mechanism 2 is used to drive the thermal insulation panels 3 to turn over, and the adjacent thermal insulation panels 3 after turning over can be spliced ​​and connected with each other. There are multiple thermal insulation panels 3, and they are arranged at intervals on the left and right.

[0043] The driving rotation mechanism 2 includes an upper worm gear 201 and a connecting rod 202. The connecting rod 202 is extended in the front-to-back direction and is rotatably arranged on the inner wall of the cavity 8. The upper worm gear 201 is fixedly sleeved on the connecting rod 202. Since the upper worm gear 201 and the first worm 11 are meshed with each other, the first worm 11 can drive the upper worm gear 201 to rotate when it rotates, and the upper worm gear 201 can drive the connecting rod 202 to rotate when it rotates.

[0044] A transparent traveling hole is opened on the rear side of the shell 1, and the traveling hole is connected with the cavity 8. The connecting rod 202 is slidably inserted in the traveling hole. The setting of the traveling hole enables the connecting rod 202 to move along the traveling hole when the multiple moving blocks 7 move evenly, thereby avoiding the connection rod 202 from being offset.

[0045] The upper worm gear 201 is located above the first worm 11 and meshes with the first worm 11. The rear side of the connecting rod 202 passes through the cavity 8 and the travel hole and is fixedly connected to the end face of the thermal insulation board 3. When the connecting rod 202 rotates, it can drive the thermal insulation board 3 to rotate, so as to achieve a plurality of adjacent thermal insulation boards 3 being flipped and spliced ​​into a top protection.

[0046] By setting the driving lifting mechanism 9, the driving rod 5 can drive the driving lifting mechanism 9 to rotate when it rotates, so that the side thermal insulation protective cloth 10 can fall down to protect the side. Specifically, a driving lifting mechanism 9 is provided on the lower side of the inner part of the cavity 8, and the driving lifting mechanism 9 is provided with a side thermal insulation protective cloth 10 (the side thermal insulation protective cloth 10 is a thickened thermal insulation cloth). The driving lifting mechanism 9 is used to drive the side thermal insulation protective cloth 10 to move up and down.

[0047] The driving lifting mechanism 9 includes a lower worm wheel 901, a first bevel gear 902, a second bevel gear 903 and a second lead screw 904. The second lead screw 904 is extended in the up and down directions. The lower worm wheel 901 is located at the lower end of the first worm 11 and is meshed with the first worm 11. Since the first worm 11 are meshed with each other, the first worm 11 can drive the lower worm wheel 901 to rotate when it rotates. The first bevel gear 902 and the second bevel gear 903 are meshed with each other. The second bevel gear 903 is fixedly mounted on the second lead screw 904. The lower worm wheel 901 can drive the first bevel gear 902 to rotate when it rotates. Since the first bevel gear 902 and the second bevel gear 903 are meshed with each other, the second bevel gear 903 can drive the second bevel gear 903 to rotate. When the second bevel gear 903 rotates, it can drive the second lead screw 904 to rotate.

[0048] A short rod 12 is rotatably provided on the inner wall of the lower side of the cavity 8 , and the lower worm wheel 901 and the first bevel gear 902 are both fixedly sleeved on the short rod 12 , and the short rod 12 can play a role in supporting the lower worm wheel 901 and the first bevel gear 902 .

[0049] A through hole 13 is provided at the bottom of the shell 1, which is transparent from top to bottom and extends in the left and right directions. The second lead screw 904 rotates to pass through the moving block 7, and the part of the second lead screw 904 that passes through the moving block 7 slides through the through hole 13 and is transmission-connected with the side thermal insulation protective cloth 10. The setting of the through hole 13 enables the moving block 7 to move evenly when it moves evenly, and the side thermal insulation protective cloth 10 is folded or unfolded.

[0050] The upper end of the side thermal insulation protective cloth 10 is hingedly connected to the bottom of the shell 1, and the side thermal insulation protective cloth 10 is sleeved on the second screw 904. The bottom of the side thermal insulation protective cloth 10 is fixedly provided with a threaded ring 14, and the threaded ring 14 is sleeved on the second screw 904 and threadedly connected to the second screw 904. Since the top of the side thermal insulation protective cloth 10 is hingedly connected to the bottom of the shell 1, and the threaded ring 14 at the bottom of the side thermal insulation protective cloth 10 is threadedly connected to the second screw 904, when the second screw 904 rotates, it can drive the threaded ring 14 to move downward. When moving, the threaded ring 14 can drive the threaded ring 14 to move downward, so as to stretch the side thermal insulation protective cloth 10 flat, thereby achieving the effect of side protection.

[0051] The setting of the driving rod 5 can not only drive the first worm gear 11 to rotate, but also make the moving block 7 and the first worm gear 11 slide along the driving rod 5. Specifically, the driving rod 5 includes a rod body 501 and a limit bar 502. The limit bar 502 is arranged in two upper and lower intervals, and the two limit bars 502 are fixedly connected to the rod body 501.

[0052] The moving block 7 and the first worm 11 are respectively provided with left and right transparent limit sliding holes, and the limit bars 502 are slidably inserted in the limit sliding holes together with the rod body 501 . When the moving block 7 moves, the moving block 7 can move along the driving rod 5 .

[0053] By setting the driving translation mechanism 4, the driving translation mechanism 4 can drive the multiple moving blocks 7 to move evenly after it is started, so as to collect the moving blocks 7 to one side or evenly distribute them on the top. Specifically, the shell 1 is provided with a driving translation mechanism 4 set in the left and right directions, and the multiple moving blocks 7 on the same side are all mounted on the driving translation mechanism 4 and are connected to the driving translation mechanism 4 in transmission. The driving translation mechanism 4 is used to drive the multiple moving blocks 7 to move evenly, and can drive the moving blocks 7 to move after it is started.

[0054] The driving translation mechanism 4 includes a third lead screw 401 and a light rod 402 , and both the third lead screw 401 and the light rod 402 are extended in the left-right direction.

[0055] The moving block 7 is provided with a limit hole which is transparent on the left and right. The third lead screw 401 and the light rod 402 are respectively inserted into the limit holes and are threadedly connected to the limit holes on the third lead screw 401. When the third lead screw 401 rotates, it can drive the moving block 7 to move along the light rod 402 so that multiple moving blocks 7 are evenly dispersed.

[0056] A second drive device 15 (the second drive device 15 is a second drive self-locking motor) is fixedly provided on the inner wall of the shell 1, and the output shaft of the second drive device 15 is fixedly connected to the third screw 401, driving the second drive device 15 to start, so that the output shaft of the second drive device 15 can drive the third screw 401 to rotate.

[0057] A scissor-type telescopic frame 16 extending in the left-right direction is hingedly provided on one side of the inner wall of the shell 1 close to the second driving device 15, and the moving blocks 7 are hingedly connected to the scissor-type telescopic frame 16. When moving, the moving blocks 7 can drive the scissor-type telescopic frame 16 to extend, so as to better enable the moving blocks 7 to move evenly.

[0058] The setting of the top layer of thermal insulation protective cloth 22 can provide double-layer protection for the precast beam during steam curing after the concrete pouring construction is completed, thereby improving the protection effect. Specifically, two fixed rods 18 are fixedly provided between the two shells 1, which are spaced left and right and extend in the front-to-back direction. A sliding groove with an upward opening is provided on the top of the fixed rod 18, and a fourth screw 19 extending along the extension direction of the sliding groove is rotatably provided in the sliding groove.

[0059] A lower sprocket 17 is fixedly provided on one side of the third lead screw 401 away from the second driving device 15 . The third lead screw 401 can drive the lower sprocket 17 to rotate while rotating.

[0060] An L-shaped groove 23 is provided in the housing 1, and an upper sprocket 20 is rotatably provided on the inner side wall of the L-shaped groove 23. A chain is meshed between the lower sprocket 17 and the upper sprocket 20. Since the lower sprocket 17 and the upper sprocket 20 are meshed with a chain, the upper sprocket 20 can be driven to rotate.

[0061] A main-stage bevel gear 24 is fixedly provided on one side of the upper sprocket 20 close to the fourth lead screw 19, and a slave-stage bevel gear 25 is fixedly provided on the fourth lead screw 19. The main-stage bevel gear 24 and the slave-stage bevel gear 25 are meshed with each other. When the upper sprocket 20 rotates, the main-stage bevel gear 24 can be driven to rotate. Since the main-stage bevel gear 24 and the slave-stage bevel gear 25 are meshed with each other, the slave-stage bevel gear 25 can be driven to rotate.

[0062] The fourth lead screw 19 is sleeved with a plurality of sliding blocks 21 which are spaced front and back and threadedly connected. The sliding blocks 21 are provided with a top layer of thermal insulation protective cloth 22 (the top layer of thermal insulation protective cloth 22 is the top layer of thermal insulation cloth). The front end of the top layer of thermal insulation protective cloth 22 is hingedly connected to the rear side of one of the shells 1. The slave bevel gear 25 drives the fourth lead screw 19 to rotate. When the fourth lead screw 19 rotates, it can drive the sliding block 21 to move along the slide groove, so that the top layer of thermal insulation protective cloth 22 is stretched, so as to achieve the effect of double protection.

[0063] Working principle: During the construction of precast beam concrete, the thermal insulation panels 3 are in a vertical state and are located on one side of the shell 1. At the same time, the side thermal insulation protective cloth 10 is folded and contracted to the side close to the bottom of the shell 1. In addition, the sliding block 21 is also located on one side of one of the shells 1, so that the top layer of thermal insulation protective cloth 22 is folded and contracted, which is convenient for the construction of precast beam concrete.

[0064] When the pouring of precast beam concrete is completed, the second driving device 15 can be driven to start first, so that the output shaft of the second driving device 15 can drive the third screw 401 to rotate. When the third screw 401 rotates, it can drive the moving block 7 to move along the light rod 402. When the moving block 7 moves, it can drive the scissor-type telescopic frame 16 to stretch, so that the moving block 7 can be better moved evenly. At the same time, the third screw 401 can also drive the lower sprocket 17 to rotate while rotating. Since the lower sprocket 17 and the upper sprocket 20 are meshed with a chain, the upper sprocket 20 can be driven to rotate. When the upper sprocket 20 rotates, the main bevel gear 24 can be driven to rotate. Since the main bevel gear 24 and the slave bevel gear 25 are meshed with each other, the slave bevel gear 25 can be driven to rotate. The slave bevel gear 25 drives the fourth screw 19 to rotate, and when the fourth screw 19 rotates, it can drive the sliding block 21 to move along the slide groove, so that the top layer of thermal insulation protective cloth 22 is stretched, so as to achieve a double protection effect.

[0065] After the moving blocks 7 are evenly dispersed, the first driving device 6 is driven to start, so that the output shaft of the first driving device 6 can drive the driving rod 5 to rotate, and the driving rod 5 can drive the first worm 11 to rotate when it rotates. Since the upper worm gear 201 and the first worm gear 11 are meshed with each other, the first worm gear 11 can drive the upper worm gear 201 to rotate when it rotates, and the upper worm gear 201 can drive the connecting rod 202 to rotate when it rotates, and the connecting rod 202 can drive the thermal insulation board 3 to rotate when it rotates, so as to achieve that multiple adjacent thermal insulation boards 3 are turned over and spliced ​​into top protection. At the same time, since the first worm gear 11 and the lower worm gear 901 are meshed with each other, the first worm gear 11 can also drive the lower worm gear 901 to rotate when it rotates, and the lower worm gear 901 can drive the first bevel gear 902 to rotate when it rotates. The second bevel gears 903 are meshed with each other, so they can drive the second bevel gear 903 to rotate. When the second bevel gear 903 rotates, it can drive the second lead screw 904 to rotate. Since the top of the side thermal insulation protective cloth 10 is hingedly connected to the bottom of the shell 1, and the threaded ring 14 at the bottom of the side thermal insulation protective cloth 10 is threadedly connected to the second lead screw 904, when the second lead screw 904 rotates, it can drive the threaded ring 14 to move downward. When the threaded ring 14 moves, it can drive the threaded ring 14 to move downward, so as to stretch the side thermal insulation protective cloth 10 flat, and play a side protection effect, so as to cover the precast beam concrete pouring construction site, and then through the steam injection head, steam can be sprayed inside for maintenance, thereby accelerating the initial setting speed of the precast beam concrete, which is faster than the natural curing speed of the precast beam concrete, so that it can be quickly demolded.
