Description

Technical Field

[0001] The present disclosure belongs to the technical field of bridge deck construction and maintenance, and particularly relates to a rigid frame bridge curing device. Background Art

[0002] After concrete pouring, when the concrete does not yet have sufficient strength, premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the curing in the initial stage after concrete pouring is very important;

[0003] For example, in the Chinese patent "A film laying machine for pavement construction curing and moisture conservation (Publication No.: CN220724794U)", the film laying machine for pavement construction curing and moisture conservation includes a first cross beam, a second cross beam, a traveling mechanism, a film laying device, a spraying device, and a brush head; the first cross beam and the second cross beam are arranged in parallel and are both mounted on the traveling mechanism arranged at both ends thereof; the first cross beam is provided with a first working platform along the extending direction; the film laying device includes a plurality of film rollers arranged in parallel to the first cross beam and sequentially arranged along the extending direction of the first cross beam. During the construction process of the film laying machine, workers can stand on the first working platform to slightly trim or finish the surface of the concrete, which is convenient for operation and avoids stepping on the concrete. After the workers slightly trim or finish the surface of the concrete, the film rollers synchronously unwind the film they have wound, realizing automatic film laying, and the film is laid longitudinally, with a faster construction speed, and can timely carry out film covering and moisture conservation for the concrete pavement;

[0004] Since the length of the laid film is relatively long, it is usually necessary to place pressing rollers at equal intervals on the laid film to prevent the film from being blown by the wind and separated from the concrete pavement; however, the above-mentioned patent "A film laying machine for pavement construction curing and moisture conservation" has the problem that it is not convenient to place pressing rollers at equal intervals on the film during film laying, and subsequent manual placement of pressing rollers is required, which not only increases the work intensity but also has low work efficiency. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the purpose of the present disclosure is to provide a rigid frame bridge curing device, which solves the problem that it is not convenient to place pressing rollers at equal intervals on the film in the prior art, realizes automatic placement of pressing rollers while laying the film, reduces the work intensity, and improves the work efficiency.

[0006] The purpose of the present disclosure can be achieved through the following technical solutions:

[0007] A rigid frame bridge curing device includes:

[0008] A vehicle frame, at the lower end of which a horizontally placed rotating roller is rotatably connected, and first rollers are fixedly sleeved at both ends of the rotating roller;

[0009] The roller is arranged at the lower end of the vehicle frame and placed coaxially with the rotating roller. Installation plates are sleeved at both ends of the roller and are rotatably connected. The installation plates are fixed to the lower end of the vehicle frame, and a film roll is sleeved on the roller.

[0010] The storage box is in the shape of a rectangular shell with an open upper end. The storage box is fixed to the vehicle frame. Multiple pressing rollers placed coaxially with the roller are stored in the storage box. Any side wall of the storage box is parallel to the roller and extends outside the vehicle frame, and a strip-shaped groove placed coaxially with the roller is formed in this side wall of the storage box.

[0011] The shaft body is placed coaxially with the strip-shaped groove, and the shaft body is rotatably connected to one side of the storage box close to the strip-shaped groove. A plurality of placement grooves are evenly distributed in a ring on the peripheral wall of the shaft body, and the placement grooves are all placed coaxially with the roller. A transmission unit is connected between the shaft body and the rotating roller.

[0012] The principle and effect of the above technical solution are as follows:

[0013] Fix the free end of the film roll on the bridge deck. By pulling the vehicle frame to move to the side away from the free end of the film roll, the film is covered on the concrete bridge deck. At the same time, during the movement of the vehicle frame, the first roller drives the rotating roller, and the rotating roller drives the shaft body through the transmission unit. The pressing roller passes through the strip-shaped groove and enters the placement groove. The pressing roller that enters the placement groove drops and is released as the shaft body rotates, so that the pressing roller drops on the film covering the concrete bridge deck. Through the linkage cooperation of the shaft body, the rotating roller and the transmission unit, the pressing rollers can be placed at equal intervals on the laid film.

[0014] Ear plates are rotatably connected to both ends of the shaft body, and the ear plates are both fixed to the storage box.

[0015] The transmission unit includes rotating shafts fixed to both ends of the shaft body. The rotating shafts are all placed coaxially with the shaft body. The rotating shafts all pass through the ear plates and are rotatably connected to them. First gears are fixedly sleeved on the rotating shafts. A pair of second gears are fixedly sleeved on the rotating roller. The second gears correspond to the first gears one by one. Annular synchronous toothed belts are sleeved between the first gears and the corresponding second gears.

[0016] An arc-shaped baffle is arranged on the side of the shaft body away from the storage box. The peripheral wall of the shaft body is in contact with the peripheral wall of the arc-shaped baffle and is rotatably connected to it. Both ends of the arc-shaped baffle are fixed to the two ear plates respectively.

[0017] A diversion plate is fixed in the storage box. The diversion plate is placed obliquely downward from the side of the storage box away from the shaft body to the side close to the shaft body. The pressing rollers are all located above the diversion plate, and the upper end surface of the diversion plate is in contact with the lower end surface of the strip-shaped groove.

[0018] Circular through holes placed coaxially with the roller are formed in the installation plates. Rolling bearings are arranged in the circular through holes. The outer rings of the rolling bearings are all fixed to the peripheral walls of the circular through holes. Discs are fixed to the inner peripheral walls of the inner rings of the rolling bearings. Both ends of the roller are detachably connected to the two discs respectively.

[0019] Threaded holes are provided at both ends of the roller, and bolts placed coaxially are threadedly connected to the discs. One end of each bolt passes through the disc and extends into the threaded hole for threaded connection therewith;

[0020] A pair of second rollers are installed at one end of the frame away from the first roller, and the second rollers are both placed coaxially with the roller;

[0021] A push rod is fixed to the frame.

[0022] Explanations for the nouns, conjunctions or adjectives involved in the above technical solutions are as follows:

[0023] Connection: It refers to the process of connecting two separated profiles or parts into a complex part or component using fasteners such as screws, bolts and rivets.

[0024] Sliding connection: Two objects are in contact but not fixed, and they can slide relative to each other.

[0025] Advantages of the present disclosure:

[0026] 1. Fix the free end of the film roll on the bridge deck. By pulling the frame to move to the side away from the free end of the film roll, the film is covered on the concrete bridge deck. At the same time, during the movement of the frame, the first roller drives the roller, and the roller drives the shaft body through the transmission unit. The pressure roller passes through the strip-shaped groove and enters the placement groove. The pressure roller that enters the placement groove drops and is released as the shaft body rotates, so that the pressure roller drops onto the film covering the concrete bridge deck. Through the linkage cooperation of the shaft body, the roller and the transmission unit, it is possible to place the pressure rollers at equal intervals on the film while laying the film, reducing labor intensity and improving work efficiency;

[0027] 2. Through the cooperative setting of the rolling bearing, the disc and the bolt, it is convenient to disassemble or install the roller, and it is convenient to replace the film roll on the roller. Description of the Drawings

By pulling the vehicle frame 100 to move to the side away from the free end of the film roll 400, the film is covered on the concrete bridge deck. At the same time, during the movement of the vehicle frame 100, the first roller 102 drives the rotating roller 101, and the rotating roller 101 drives the shaft body 700 through the transmission unit 800. The pressing roller 600 passes through the strip-shaped groove 501 and enters the placement groove 701. The pressing roller 600 entering the placement groove 701 drops and is released as the shaft body 700 rotates, so that the pressing roller 600 drops onto the film covering the concrete bridge deck. Through the linkage cooperation of the shaft body 700, the rotating roller 101 and the transmission unit 800, the pressing roller 600 can be placed at equal intervals on the laid film.

[0036] Please refer to Figures 1 to 5 , a rigid frame bridge curing device, comprising:

[0037] A vehicle frame 100, the lower end of the vehicle frame 100 is rotatably connected with a horizontally placed rotating roller 101, and both ends of the rotating roller 101 are fixedly sleeved with first rollers 102;

[0038] A winding roller 200, the winding roller 200 is arranged at the lower end of the vehicle frame 100 and is coaxially placed with the rotating roller 101. Both ends of the winding roller 200 are sleeved with rotatably connected mounting plates 300, the mounting plates 300 are fixed to the lower end of the vehicle frame 100, and a film roll 400 is sleeved on the winding roller 200;

[0039] Storage box 500, the storage box 500 is in the shape of a rectangular shell with an open upper end. The storage box 500 is fixed to the vehicle frame 100. A plurality of pressure rollers 600 placed coaxially with the winding roller 200 are stored in the storage box 500. Any side wall of the storage box 500 is parallel to the winding roller 200 and extends to the outside of the vehicle frame 100, and a strip-shaped groove 501 placed coaxially with the winding roller 200 is formed in the side wall of the storage box 500 on this side;

[0040] Shaft body 700, the shaft body 700 is placed coaxially with the strip-shaped groove 501, and the shaft body 700 is rotatably connected to one side of the storage box 500 close to the strip-shaped groove 501.

A transmission unit 800 is connected between the shaft body 700 and the rotating roller 101;

[0041] The film roll 400 is used to be laid on the preliminarily solidified concrete bridge deck to prevent the moisture in the concrete from evaporating too quickly and causing cracks in the concrete bridge deck. The film roll 400 formed by winding a film made of polyethylene material can be selected. The film made of this material has good waterproof and moisture retention properties.

[0042] The storage box 500 is used to place the pressure rollers 600. The length of the inner side of the storage box 500 along the axis direction of the winding roller 200 is equal to the length of the pressure rollers 600. The material of the storage box 600 can be selected from plywood, particle board, etc., or traditional metal materials such as steel and aluminum alloy.

[0043] The length of the placement groove 701 formed on the shaft body 700 is greater than the length of the pressure roller 600. Preferably, only one pressure roller 600 can be placed in the placement groove 701 at a time. The preferred material of the shaft body 700 is aluminum alloy, which has low density, high strength, good plasticity, and low price
