Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an elevator shaft concrete pouring inner formwork supporting device. Background Art
[0002] The elevator shaft, referred to as "hoistway", is a vertical passage in a building for elevators to travel up and down. The cross section is rectangular or square. The shaft is equipped with guide rails for the elevator car and counterweight to slide. The bottom pit of the shaft is equipped with buffers for the elevator car. The motor and transmission machinery are mostly installed at the top of the shaft.
[0003] In the prior art, the elevator car and the elevator car accessories are installed inside the elevator shaft. Before installing the elevator car and the elevator car accessories, it is necessary to reserve the elevator shaft inside the building and pour the elevator shaft with concrete. In the early stage of pouring the elevator shaft with concrete, it is necessary to support the inner wall of the elevator shaft with an inner formwork to facilitate the molding of the elevator shaft. In order to better mold the elevator shaft, it is necessary to support the inner formwork. The existing inner formwork support is generally supported by building a support frame. This method of support takes a lot of time to build and dismantle, and the supporting effect is also relatively poor. Therefore, we propose an elevator shaft concrete pouring inner formwork support device. Utility Model Content

[0011] As a preferred solution of the utility model, the second electric push rods are symmetrically installed inside the supporting rollers, and the output ends of the second electric push rods are fixedly connected to the longitudinal supporting rollers.
[0012] The technical effect of adopting the above further solution is: the longitudinal support roller can be effectively squeezed and pushed by the second electric push rod, so that the longitudinal support roller can support and fix the inner template.

[0023] Example 1
[0024] like Figure 1-3As shown, the utility model provides a technical solution: an elevator shaft concrete pouring inner formwork support device, comprising two rectangular bases 1 arranged opposite to each other up and down, a first electric push rod 2 is installed on the opposite side of the base 1, and a rectangular extension seat 3 is symmetrically installed on both sides of the base 1, and support rollers 4 are symmetrically installed on both sides of the extension seat 3, and transverse support rollers 5 are installed on the opposite side of the support roller 4, and longitudinal support rollers 6 are symmetrically installed on the front and back sides of the support roller 4.
[0025] Example 2
[0026] like Figure 1-3 As shown, a linear guide rail 31 is provided on the top of the extension seat 3, and a screw slider 32 is slidably connected inside the linear guide rail 31, and a mounting plate 33 is installed on the top of the screw slider 32, and the mounting plate 33 can be driven to move by the screw slider 32.
[0027] A lead screw 34 that intersects with the thread of the lead screw slider 32 is also rotatably connected inside the linear guide 31, and a drive motor 35 whose output end passes through the linear guide 31 and is fixedly connected to the lead screw 34 is also installed inside the extension seat 3. The drive motor 35 can effectively drive the lead screw 34 to rotate, thereby driving the lead screw slider 32 to move in the linear guide 31.
[0028] Auxiliary sliders 331 are symmetrically installed at the bottom of the mounting plate 33, and auxiliary slide grooves 332 are correspondingly opened on the periphery of the auxiliary sliders 331 and at the top of the extension seat 3. The auxiliary sliders 331 slide in the auxiliary slide grooves 332, which can effectively improve the stability of the movement of the mounting plate 33.
[0029] A cylindrical first support shaft 41 is symmetrically mounted on one side of the support roller 4 close to the mounting plate 33 , and five second support shafts 42 are equidistantly mounted on one side of the support roller 4 away from the mounting plate 33 . The second support shafts 42 are fixedly connected to the transverse support roller 5 .
[0030] The second electric push rods 43 are symmetrically installed inside the support rollers 4, and the output ends of the second electric push rods 43 are fixedly connected to the longitudinal support rollers 6, which can provide supporting force and are also convenient for adjustment according to the size of the elevator shaft.
[0031] The working process of the utility model is as follows: when using an elevator shaft concrete pouring inner formwork support device for inner formwork support, first, the device is placed inside the elevator shaft, and then the first electric push rod 2 is controlled to lift the top base 1 according to the height of the inner formwork. After completion, the drive motor 35 is controlled to drive the screw rod 34 to rotate, thereby driving the screw rod slider 32 to move in the linear guide rail 31. As the screw rod slider 32 moves, the mounting plate 33 is also moving, and the first support shaft 41 is pushed by the movement of the mounting plate 33, and the first support shaft 41 is pushed by the first support The shaft 41 pushes the support roller 4. After the support roller 4 is pushed, the transverse support roller 5 connected by the second support shaft 42 is also pushed toward the inner template and supports it. When the transverse support roller 5 is unfolded, the longitudinal support roller 6 also retracts and contracts accordingly. When the transverse support roller 5 has completed its support, the second electric push rod 43 pushes the longitudinal support roller 6 to enable the longitudinal support roller 6 to support the inner template in the same direction. The utility model can effectively support the inner template of the elevator shaft through its design, with good supporting effect and no need for construction and dismantling, which is very convenient and efficient.
