Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to a pouring system for the cooling tower wall. Background Art

[0002] During the construction of large cooling towers, the tower body structure has significant engineering characteristics. Its pouring height can reach 150 meters, the diameter range is 32.8 - 54.77 meters, and the pouring thickness is 0.2 - 1 meter. During construction, formwork support processes such as slip formwork or climbing formwork need to be used, and steel bar binding and concrete pouring operations are completed within the installed formwork. Since the operation layer is on the high-altitude formwork support, construction workers need to complete the concrete transfer operation within a circular operation passage with a width of only about 0.6 meters. This special operation environment poses strict requirements on the mobility, safety, and operation efficiency of concrete transfer equipment. The material transportation in the narrow high-altitude space has become the core link restricting the construction progress and safety.

[0003] Currently, the industry generally adopts a two-stage concrete transportation plan: First, the ground-prepared concrete is pumped to the high-altitude operation layer through a cement pump truck via a vertical pipeline, and then the concrete is distributed to each pouring point along the circular passage by manually pushing a cement transfer truck. Existing transfer trucks mostly adopt a four-wheel structure, with the same diameter of the inner and outer wheels, and rely on manual pushing to achieve short-distance horizontal transportation. Although this method can complete the basic transfer function, it is found in practical applications that its mechanical design and operation mode have significant limitations, and it is difficult to meet the requirements of efficient construction, especially in the complex working conditions of narrow high-altitude passages.

[0004] The existing technology has the following prominent problems: First, manually pushing the transfer truck requires a lot of physical strength and needs multiple people to cooperate. During continuous operation, it is easy to cause fatigue of workers, and the transfer efficiency decreases significantly as the operation time prolongs. Second, the design of equal-diameter inner and outer wheels results in an inability to match the linear speed difference between the inner and outer wheels when the vehicle turns in the circular passage, which is prone to lateral deviation or even unilateral wheel suspension. Coupled with the channel width of only 0.6 meters, there is a safety hazard that the vehicle may rush out of the operation surface and cause a high-altitude fall. In addition, the existing transfer truck lacks an active driving device and a deviation correction system, and it is difficult to achieve precise positioning and stable operation in the complex high-altitude environment, seriously restricting the construction quality and progress control of super-high cooling towers.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0026] An embodiment of the present application discloses a pouring system for the wall of a cooling tower. Referring to Figure 1 and Figure 2 , the cooling tower body 1 is formed by stage-by-stage pouring from the bottom to the top. After the concrete poured in the previous stage solidifies and forms, a pouring formwork is continued to be built on its basis, and a circular support 21 (a simplified schematic diagram in the figure) is built on the periphery of the formwork for on-site pouring construction. The pouring system of the present application is built on the circular support 21.

[0027] Referring to Figure 2 and Figure 3 , the pouring system for the wall of the cooling tower includes: a pouring vehicle 4 and a pouring track 3. The pouring track 3 surrounds the periphery of the cooling tower formwork 2. The pouring vehicle 4 includes: a vehicle body 41 for carrying pouring materials, and a pouring outlet 411 is provided on its side; a pouring guide plate 414 fixedly arranged on the vehicle body 41 for guiding the pouring materials flowing out of the pouring outlet 411 into the cooling tower formwork 2. It is a U-shaped plate and is arranged obliquely downward to facilitate the flow of concrete; a traveling device arranged at the bottom of the vehicle body 41 for restricting and driving the vehicle body 41 to travel along the pouring track 3; a gate 413 slidably arranged on the vehicle body 41 for opening or closing the pouring outlet 411; a switch device 5 for controlling the sliding of the gate 413; a control area located at the tail of the vehicle body 41 for a driver to control the traveling system and the switch device 5.

[0028] In the present application, the traveling device restricts and drives the vehicle body 41 to travel along the pouring track 3. The staff is located in the driving area to control the vehicle to travel, and the switch device 5 is used to control the sliding of the gate 413 to control the opening size of the pouring opening at any time, so as to control the pouring discharge. When the concrete in the vehicle body 41 is discharged completely, the vehicle body 41 is controlled to return to the pouring point, and the concrete is pumped through a concrete pipeline, and the pouring work is continued. The semi-automatic pouring method can greatly improve the pouring efficiency of the cooling tower formwork 2, thereby improving the convenience of pouring the cooling tower formwork 2.

[0029] Specifically, as Figure 3As shown, the cross-sectional area of the vehicle body 41 gradually expands from the top to the bottom, which can minimize the center of gravity of the vehicle body 41 when fully loaded, improve the stability of the vehicle body 41 when driving, and the inclined front of the vehicle can also reduce the resistance of the vehicle body 41 when moving forward.

[0030] Furthermore, the traveling device includes a traveling wheel 42 , a traveling drive 43 and a limiting assembly 44 .

[0031] The running wheels 42 are the main bearing units when the vehicle body 41 is running. The running wheels 42 are symmetrically arranged on both sides of the vehicle body 41, and two groups are arranged along the front and rear ends of the vehicle body 41. A wheel axle 421 is coaxially fixed between the two running wheels 42 in the same group. The wheel axle 421 is rotatably arranged at the bottom of the vehicle body 41 through a bearing bracket. In order to solve the problem of the wheel speed difference between the outer running wheel 42 and the inner running wheel 42 when the vehicle body is running in a circular track around the casting track 3, in this embodiment, the diameter of the running wheel 42 close to the outer side of the vehicle body 41 is larger than the diameter of the running wheel 42 close to the inner side of the vehicle body 41, so that the speed difference between the inner and outer running wheels 42 is adapted to the curvature of the casting track 3. As an alternative embodiment, the casting track 3 can also be designed to be higher on the outer side than on the inner side, which can also solve the problem of the speed difference between the inner and outer running wheels 42 when the vehicle body is moving in a circular track.

[0032] The travel drive 43 is a relatively conventional wheel axle drive device, which is fixedly connected to the wheel axle 421 through a reduction gear set, and is equipped with a motor as a power source, and is equipped with a battery to power the motor. In this embodiment, the travel drive 43 is set on the axle of the front travel wheel 42, such as Figure 4 As shown, the rear end running wheel 42 is provided with a steering device (which is a conventional prior art and will not be expanded here). The design of front wheel drive and rear wheel steering is suitable for flexibly adjusting the direction on the narrow annular bracket 21, adapting to the steering of the casting track 3, and can give consideration to both traction and stability. It is suitable for the annular track of cooling tower casting and the working conditions of low speed and heavy load; The limiting assembly 44 is disposed at the bottom of the vehicle body 41 and is used to limit the running wheels 42 from running along the casting track 3 to prevent the running wheels 42 from leaving the casting track 3 .

[0033] Specifically, refer to Figure 5 and Figure 6, the pouring track 3 includes a track base 31 and two guide rails 32 symmetrically arranged on the track base 31. The entire pouring track 3 is divided into multiple segments and assembled into a ring, and surrounds the circumference of the cooling tower formwork 2. The track base 31 is fixed to the ring bracket 21 by bolts. The guide rail 32 includes a support portion 321 and a top plate 322. The support portion 321, the top plate 322 and the track base 31 are integrally formed. The top plate 322 is located at the top of the support portion 321. The side of the top plate 322 close to the other guide rail 32 protrudes from the support portion 321 below it. A limiting flange 33 is provided on the side of the top plate 322 close to the vehicle body 41, which can limit the traveling wheels 42 when the operation is improper, and prevent the traveling wheels 42 from entering between the two guide rails 32, causing derailment construction accidents.

[0034] In addition, the limiting component 44 includes a limiting wheel 441, a limiting bracket 442 and a sliding drive. The sliding bracket is in an inverted U shape. Two limiting wheels 441 are respectively rotatably connected to both ends of the limiting bracket 442. The limiting bracket 442 is slidably connected to the vehicle body 41 in the transverse direction. The sliding drive is used to drive the limiting bracket 442 to slide between the limiting state and the storage state. The periphery of the limiting wheel 441 is made of elastic material, and the edge part of the limiting wheel 441 is chamfered, which is convenient for placing the limiting wheel 441 from the side of the top plate 322 to the bottom of the top plate 322, and making the limiting wheel 441 fit the bottom of the cross plate, so that the limiting wheel 441 has a certain extrusion space, improving fault tolerance, and the elastic limiting wheel 441 can rely on its own elasticity to keep the limiting wheel 441 always close to the bottom surface of the top plate 322.

[0035] When the limiting bracket 442 is in the limiting state, the limiting wheel 441 adheres to the bottom surface of the top plate 322, and cooperates with the traveling wheels to clamp the top plate 322 up and down, so that the vehicle body 41 is limited vertically, and cooperates with the transverse limit of the limiting flange 33 to realize the stable traveling of the vehicle body 41 along the pouring track 3. While improving the pouring efficiency, it can greatly improve the safety of high-altitude operations. When the limiting bracket 442 is in the storage state, the limiting wheel 441 is staggered from the top plate 322, which is convenient for installing the pouring vehicle 4 on the pouring track 3, and also convenient for detaching the pouring vehicle 4 from the pouring track 3.

[0036] In order to further improve the traveling stability of the vehicle body 41, two limiting brackets 442 are provided and respectively correspond to the two guide rails 32, and the sliding drive can drive the two limiting brackets 442 to slide synchronously closer to or away from each other.

[0037] Specifically, as Figure 6As shown in the figure, the sliding drive includes a bidirectional screw 443, a guide rod 444, and a drive motor 447. The bidirectional screw 443 is arranged in parallel with the guide rod 444, and both are parallel to the wheel axle 421 of the front driving wheel 42. The bidirectional screw 443 is rotatably arranged in the middle part at the bottom of the vehicle body 41 through bearings and mounting brackets. A threaded seat 4421 is arranged in the middle part of the limit bracket 442. A threaded hole is opened in the middle of the threaded seat 4421. The two limit brackets 442 are respectively threadedly connected to both ends of the bidirectional screw 443 through their own threaded seats 4421. There are two guide rods 444, and they are symmetrically arranged with respect to the lateral center plane of the limit bracket 442. The guide rods 444 are fixedly connected to the bottom of the vehicle body 41 through mounting brackets and penetrate through the two limit brackets 442. The drive motor 447 is used to drive the bidirectional screw 443 to rotate.

[0038] When it is necessary to drive the limit bracket 442 to slide, the bidirectional threaded rod is driven to rotate by the drive motor 447, so that the two limit brackets 442 move closer to or away from each other under the engagement of the threads. The guide rod 444 limits the limit bracket 442 to make the limit bracket 442 move stably.

[0039] In order to save space, the drive motor 447 should be avoided being arranged on the side of the bidirectional screw 443. Therefore, in this embodiment, a gear one 445 and a gear two 446 are arranged between the drive motor 447 and the bidirectional screw 443. The gear one 445 and the gear two 446 are meshed. The gear one 445 is coaxially fixed to the middle part of the bidirectional screw 443. The gear two 446 is rotatably connected to the vehicle body 41 through a mounting bracket. The drive motor 447 is fixedly arranged on the vehicle body 41 through a mounting bracket and bolts. The output end of the drive motor 447 is coaxially fixed to the gear two 446 to drive the gear two 446 to rotate and drive the gear one 445 to rotate, so as to realize driving the bidirectional screw 443 to rotate. This design layout makes the drive motor 447 arranged in the middle part at the bottom of the vehicle body 41 and located between the two guide rails 32 without interfering with the guide rails 32, thus effectively saving the lateral occupied space of the vehicle body 41. Moreover, by adjusting the ratio of the gear one 445 and the gear two 446, the transmission efficiency and transmission torque of the drive motor 447 driving the bidirectional screw 443 can be adjusted.

[0040] On the other hand, referring to Figure 3 , two limit tracks 412 are arranged on both sides of the vehicle body 41 and the gate 413. A chute adapted to the thickness of the gate 413 is opened on one side of the two tracks close to each other. The bottom of the chute is sealed and the top is open, so that the gate plate automatically slides to the bottom of the chute under the action of gravity to block the pouring opening.

[0041] As Figure 4As shown, the switch device 5 includes a connecting rod 1 51, a connecting rod 2 52 and a rotating shaft 53. The first end of the connecting rod 1 51 is hinged to the gate 413, and the second end is hinged to the first end of the connecting rod 2 52. The rotating shaft 53 is fixedly connected to the vehicle body 41 and passes through the connecting rod 2 52 from the side of the connecting rod 2 52, so that the connecting rod 2 52 can rotate around the rotating shaft 53. In order to facilitate the driver to control the gate 413, the second end of the connecting rod 2 52 extends into the control area.

[0042] A handle 54 is disposed at the second end of the connecting rod 52. The handle 54 is made of elastic material such as rubber or silicone, which can effectively improve the comfort level of the operator.

[0043] In this embodiment, the distance between the rotating shaft 53 and the first end of the second connecting rod 52 is greater than the distance between the rotating shaft 53 and the second end of the second connecting rod 52. Through the lever principle, the amplitude of the second connecting rod 52 to be moved by the driver when opening the gate 413 can be reduced, so that the driver can control the opening amplitude of the gate 413 while sitting in the driver's seat. As an alternative embodiment, the distance between the rotating shaft 53 and the first end of the second connecting rod 52 is less than the distance between the rotating shaft 53 and the second end of the second connecting rod 52. This design has the effect of saving effort, but when opening the gate 413, the rotation amplitude of the second connecting rod 52 needs to be larger.

[0044] The control area includes a support base plate 45, a driver's seat 47 and a controller 48. The support base plate 45 is welded and fixed to the rear of the vehicle body 41. Side plates 46 are welded and fixed on both sides of the support base plate 45. The side plates 46 are welded and fixed to the rear end surface of the vehicle body 41 and the support base plate 45, which can improve the stability of the support base plate 45 structure. The driver's seat 47 includes a seat plate and a cushion. The seat plate is fixedly mounted on the support base plate 45, and the cushion is fixed on the seat plate. The controller 48 is fixed to the rear end of the vehicle body 41 and is located in front of the driver's seat 47. The controller 48 is electrically connected to the driving device. The controller 48 is provided with a control button. The driver controls the vehicle body 41 to move forward, backward and turn through the control button, and controls the limit bracket 442 to slide. The driver can also control the lifting and lowering of the gate 413 by the connecting rod 2 52 extending into the control area, so as to greatly improve the convenience of controlling the pouring vehicle 4 and improve the efficiency of pouring the cooling tower template 2.

[0045] In addition, a solar panel 415 is installed on the vehicle body 41 to supply power to the battery on the vehicle body 41 and to supply power to various electrical appliances of the vehicle body 41 so that the pouring vehicle 4 can operate sustainably.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
