[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-6 As shown, an easily adjustable box culvert steel formwork hoisting machine includes a gantry frame 100, which comprises two triangular frames 101. A crossbeam 102 is welded between the tops of the two triangular frames 101. Each triangular frame 101 has a first wheel 103 at its bottom. Steel rails are laid on the construction site, allowing the gantry frame 100 to move along the rails via the first wheels 103. The first wheels 103 have a braking function, and their axles are connected to the output of a drive motor. The drive motor rotates the first wheels 103, causing the gantry frame 100 to move along the rails. A sliding frame 200 is slidably connected to the crossbeam 102. A suspension assembly 300 is located at the center of the bottom of the sliding frame 200. Hanging rods 400 are fixedly installed at the four corners of the bottom of the sliding frame 200. Clamping assemblies 500 are fixedly installed at the bottom of the hanging rods 400. An auxiliary support 600 is located at the top of the sliding frame 200.

[0031] The cross-section of the crossbeam 102 is I-shaped, and the cross-section of the sliding frame 200 is U-shaped. Two second wheels 201 are installed on the front and rear inner walls of the sliding frame 200. One of the second wheels 201 is fixedly mounted with a first motor 202. The second wheel 201 rolls against the lower half of the crossbeam 102. Specifically, the lower half of the crossbeam 102 has a track for the wheel 201 to travel on, with limit and anti-collision mechanisms at both ends of the track. The first motor 202 drives one of the second wheels 201 to rotate, causing the sliding frame 200 to slide back and forth along the crossbeam 102. In practice, the second wheel 201 is also a wheel with a braking function. Specifically, a hydraulic brake can be installed on the second wheel 201. The hydraulic brake includes a brake disc, brake pads, and a hydraulic cylinder. The second wheel 201 is coaxially fixed to the brake disc. The hydraulic pressure of the hydraulic cylinder drives the brake pads to press tightly against the surface of the brake disc. The friction between the brake pads and the brake disc brakes the second wheel 201.

[0032] In use, the suspension assembly 300 includes a second motor 301 fixedly installed at the bottom of the sliding frame 200. A winding wheel 302 is fixedly installed at the output end of the second motor 301. A first steel cable 303 is provided on the winding wheel 302. A connecting column 304 is fixedly installed at the bottom end of the first steel cable 303. Two V-shaped holes 305 are formed through the circumference of the connecting column 304. The V-shaped holes 305 are inclined, with the two openings of the V-shaped holes 305 tilting downwards. A second steel cable 306 is threaded through each V-shaped hole 305. Hooks 307 are fixedly installed at both ends of the second steel cable 306. When suspending the box culvert steel formwork, the hooks 307 at both ends of the second steel cable 306 are hung on the box culvert steel formwork. The second steel cable 306 can then slide within the V-shaped holes 305, so that the connecting column 304 is positioned above the middle of the box culvert steel formwork, facilitating the balance of the box culvert steel formwork. Then, the second motor 301 drives the winding wheel 302 to rotate, winding or releasing the first steel cable 303, thereby driving the box culvert steel formwork to move up and down.

[0033] In actuality, the clamping assembly 500 comprises a support frame 501 fixedly installed at the bottom of the boom 400, two guide rods 502 fixedly installed between the left and right side walls of the support frame 501, two clamping plates 503 slidably connected to the guide rods 502 and distributed left and right. The upper portions of the left and right ends of the support frame 501 are provided with mounting collars 516, the left side of the support frame 501 is fixedly installed with a third motor 504, the output end of the third motor 504 is fixedly installed with a threaded rod 505, the threaded rod 505 is in a light rod structure and passes through the left and right mounting collars 516, a bearing is arranged between the threaded rod 505 and the mounting collars 516, so that the threaded rod 505 can rotate in the mounting collars 516, the left half and the right half of the threaded rod 505 are opposite in screw direction, the top of each clamping plate 503 is fixedly installed with a threaded sleeve 506, and the two threaded sleeves 506 are threadedly connected to the left half of the threaded rod 505 and the right half of the threaded rod 505 respectively. After the suspension assembly 300 suspends the box culvert steel formwork to a certain height, the third motor 504 is driven to rotate the threaded rod 505, so as to drive the two clamping plates 503 to move towards each other along the guide rods 502, so that the two clamping plates 503 are clamped on the two sides of the box culvert steel formwork. Therefore, when the gantry 100 moves on the steel rail or the sliding frame 200 moves along the cross beam 102, the clamping plate 503 can move together with the box culvert steel formwork, avoiding that the first steel cable 303 is inclined when the first steel cable 303 drives the box culvert steel formwork to move, and causing the box culvert steel formwork to shake.

[0034] The middle portion of the guide rod 502 is provided with a bent portion 507, the bent portion 507 is bent towards the center of the support frame 501, two reinforcing rods 508 are fixedly installed between the front and rear side walls of the middle portion of the support frame 501, the reinforcing rods 508 penetrate through the bent portions 507, the two reinforcing rods 508 and the two bent portions 507 cross and enclose a frame-shaped structure, and the first steel cable 303 penetrates through the frame-shaped structure. The frame-shaped structure limits the first steel cable 303, preventing the first steel cable 303 from shaking in a large range. The support frame 501 is fixedly installed with a protective cover 509, the protective cover 509 covers the upper sides of the threaded rod 505 and the threaded sleeve 506 and is used for shielding rainwater and the like. The bottom of the protective cover 509 is provided with an opening for avoiding the moving path of the threaded sleeve 506.

[0035] Specifically, the clamping assembly 500 further comprises two U-shaped frames 510, which are distributed left and right, and two vertical rods 511 are fixedly installed on each U-shaped frame 510, and the vertical rods 511 are slidingly connected to the support frame 501, so that the U-shaped frame 510 can move up and down relative to the support frame 501. A swing arm 512 is hinged between the bottom middle part of the U-shaped frame 510 and the top middle part of the clamping plate 503, so that when the two clamping plates 503 move towards each other, the U-shaped frame 510 is pushed downward by the swing arm 512. A sleeve 513 is fixedly installed at the bottom center of the U-shaped frame 510, a pressing rod 514 is slidingly connected to the bottom end of the sleeve 513, and a first spring 515 is fixedly installed between the top end of the pressing rod 514 and the top wall of the sleeve 513. When the U-shaped frame 510 moves downward, the pressing rod 514 is attached to the top of the box culvert steel formwork, and as the U-shaped frame 510 moves downward, the first spring 515 is squeezed and contracted. Through the elasticity of the first spring 515, the squeezing force of the pressing rod 514 on the box culvert steel formwork is increased, so that the first steel cable 303 is tightened, and the box culvert steel formwork is more stable.

[0036] In reality, the auxiliary support 600 comprises a top plate 601 fixedly installed on the top of the sliding frame 200, the top plate 601 is in the shape of a "J" in cross section, sliding rods 602 are slidingly connected to the middle part of both ends of the top plate 601, a supporting plate 603 is fixedly installed between the bottom ends of the two sliding rods 602, second springs 604 are arranged between the top of the supporting plate 603 and the top wall of the top plate 601, pressing wheels 605 are arranged at the bottom of the supporting plate 603, and the pressing wheels 605 are attached to the top of the cross beam 102. Through the elasticity of the second springs 604, the pressing wheels 605 are attached to the top of the cross beam 102. And the second wheels 201 have a tendency to move away from the cross beam 102; after the suspension assembly 300 is connected to the box culvert steel formwork at the bottom, under the pulling action of the box culvert steel formwork, the top plate 601 and the second wheels 201 move downward until the second wheels 201 are attached to the lower half of the cross beam 102. A part of the weight of the box culvert steel formwork is applied to the lower half of the cross beam by the second wheels 201, and the other part of the weight of the box culvert steel formwork is applied to the top of the cross beam 102 by the pressing wheels 605.

[0037] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
