Description

Technical Field

[0001] The utility model belongs to the field of building construction, and more specifically relates to a cart for transporting concrete. Background Art

[0002] The field of construction technology is dedicated to the management and implementation of construction projects from planning to completion. Its goal is to effectively organize and manage the construction process through scientific methods and advanced tools, ensuring projects are completed on time, to quality, and on budget. This field encompasses a wide range of aspects, including project planning, material selection, construction processes, safety management, and cost control. Construction processes primarily involve the handling, mixing, and transportation of reinforced concrete. Specifically, handling reinforced concrete primarily refers to the use of mechanical equipment such as cranes, elevators, and conveyor belts to move materials to designated locations. Mixing concrete primarily involves the mixing of cement, sand, and gravel using equipment such as concrete mixing plants, automated control systems, and high-efficiency mixing equipment. Transportation of concrete involves transporting the mixed concrete to other flat areas or to the base of cranes and elevators using carts, where it is hoisted by ropes fixed to the carts and delivered to designated floors.

[0003] Existing manual push carts typically have lifting lugs welded to either side of the cart body, with a rope welded to the lugs. When the cart needs to be lifted, the crane hook directly hooks the rope and lifts the cart. Concrete easily solidifies when exposed to sunlight, and concrete lumps easily stick to the rope, adding to the strain on the rope and compromising its reliability over time. After a period of use, the cart body needs to be cleaned to reduce the burden on construction workers. Concrete lumps stuck to the rope increase the cleaning burden. Furthermore, the presence of the rope makes it easy for construction workers to collide with the shovel as they shovel concrete into the cart body, placing a significant burden on the workers and affecting loading efficiency. Furthermore, because the cart body is an integrated design, cleaning the cart body requires turning it upside down to allow wastewater to drain. This cumbersome process, coupled with the need to tip the cart body over, can cause safety accidents, resulting in injuries to construction workers caused by the cart body. Utility Model Content

[0004] The main purpose of the present application is to provide a concrete transport cart. By installing a rope retraction assembly on the side of the car body, the rope can be retracted and released at any time. When concrete needs to be loaded, the rope is retracted to avoid collision between the shovel and the rope. At the same time, a baffle that can be opened and closed at will is provided on one side of the car body. When waste water needs to be discharged, the baffle can be opened to discharge the waste water, thereby avoiding accidents caused by personal injury due to the inverted car body.

[0005] In order to achieve the above objectives, the present application proposes a concrete transport cart, comprising:

[0006] carriages, for loading concrete;

[0007] Rope retracting and releasing assemblies are fixed on both sides of the carriage, and are arranged adjacent to the concrete transportation direction. Ropes are installed in the rope retracting and releasing assemblies, and can drive the ropes to be retracted and released;

[0008] A baffle is provided on one side of the carriage, adjacent to the rope retracting assembly. A flow outlet is provided on the carriage on the side in the forward direction of concrete transportation. One end of the baffle is hinged to the flow outlet, and a sealing rubber ring is provided at the flow outlet.

[0009] The locking pin assembly is respectively installed on the baffle and the panel of the outflow port, and is used to open and close the baffle.

[0010] Furthermore, the rope retracting assembly includes:

[0011] a box body with a hinged lid secured to one side of the carriage;

[0012] A rotating shaft is hung in the box body in a direction perpendicular to the direction of the rope retraction and release, and rotates relative to the box body, one end of the rotating shaft extends to the outer end of the box body, and the extended end is fixedly connected to the handwheel;

[0013] A rope, one end of which is fixed to the rotating shaft and is wound around the rotating shaft along the circumferential direction of the rotating shaft, and a hanging portion is provided at the head of the rope;

[0014] The isolation plate is fixedly installed in the box body and arranged parallel to the rotating shaft. The isolation plate is provided with an inlet and outlet. The rope passes through the inlet and outlet, and the hanging part is limited by the inlet and outlet.

[0015] The hinged cover can be flipped over and placed over the box when the rope is not in use, preventing concrete from entering the box and ensuring that the components inside are not affected. The isolation plate not only limits the hanging part of the rope from entering the rotating shaft, but also further prevents concrete particles from entering the area near the rotating shaft.

[0016] Furthermore, a lifting lug is provided on one side of the carriage adjacent to the box body, and a receiving cavity is provided in the box body. A balancing rope is placed in the receiving cavity, and the balancing rope is used to be connected to the hook of the crane to balance the carriage.

[0017] Furthermore, a slide is provided on the inner wall of the box, a storage box is provided in the storage cavity, the storage box is slidably connected to the slide, and the balance rope is placed in the storage box.

[0018] In order to facilitate the storage of the balance rope and prevent the balance rope from being lost, the present solution provides a sliding storage box for storing the balance rope.

[0019] Furthermore, a limiting groove is provided in the middle of the lifting ear for limiting the balance rope.

[0020] The limiting groove can limit the displacement of the balance rope, thereby further reducing the shaking or tilting of the cart during the lifting process.

[0021] Furthermore, both ends of the balance rope are provided with an annular fixing portion, wherein the annular fixing portion at one end can pass through the annular area of ​​the annular fixing portion at the other end.

[0022] When using the balance rope, you can pass it through the lifting eye and then pass the small diameter end through the large diameter end to lock the lifting eye, and then put the large diameter end into the hook of the crane for lifting.

[0023] Furthermore, the locking pin assembly includes:

[0024] A fixing seat, fixedly mounted on the baffle, wherein the fixing seat is provided with a socket;

[0025] A latch seat is fixedly mounted on the panel of the outflow port, and a pin hole is provided on the latch seat;

[0026] The elastic latch is inserted into the socket and the pin hole. When the elastic latch is separated from the socket, the baffle is opened.

[0027] The elastic latch can be used repeatedly, thereby improving the stability and reliability of the lock pin assembly.

[0028] Furthermore, the elastic latch comprises:

[0029] A latch member, which passes through the fixing seat and the latch seat through the socket and the pin hole, and a limit pin is installed on one end of the latch member facing the fixing seat;

[0030] The spring is wound around the latch member, is limited by the limiting pin, and is arranged on the latch seat.

[0031] The concrete transport cart proposed in this utility model has the following beneficial effects:

[0032] (1) By installing a rope retraction assembly on the side of the vehicle body, the rope can be retracted and released at any time. When concrete needs to be loaded, the rope is retracted to avoid collision between the shovel and the rope. At the same time, a baffle that can be opened and closed at will is provided on one side of the vehicle body. When waste water needs to be discharged, the baffle can be opened to discharge the waste water, thereby avoiding accidents caused by the inverted vehicle body causing injuries to people.

[0033] (2) The utility model provides a lifting lug on the side of the carriage adjacent to the rope retraction assembly, and a receiving chamber is provided in the box body. A balancing rope is placed in the receiving chamber. The balancing rope is used to connect to the hook of the crane to balance the carriage. When construction workers use the hook of the crane to lift the carriage, since the existing carriage is only subjected to force at both ends, the cart is prone to tilting or shaking during the upward lifting process, causing concrete to fall and easily injuring nearby construction workers. Therefore, by providing a balancing rope, the carriage can be subjected to force in all four directions, thereby achieving force balance and effectively reducing the tilting or shaking of the cart.

[0049] Example

[0050] Existing manual push carts typically have lifting lugs welded to either side of the cart body, with a rope welded to the lugs. When the cart needs to be lifted, the crane hook directly hooks the rope and lifts the cart. Concrete easily solidifies when exposed to sunlight, and concrete lumps easily stick to the rope, adding to the strain on the rope and compromising its reliability over time. After a period of use, the cart body needs to be cleaned to reduce the burden on construction workers. Concrete lumps stuck to the rope increase the cleaning burden. Furthermore, the presence of the rope makes it easy for construction workers to collide with the shovel as they shovel concrete into the cart body, placing a significant burden on the workers and affecting loading efficiency. Furthermore, because the cart body is an integrated design, cleaning the cart body requires turning it upside down to allow wastewater to drain. This cumbersome process, coupled with the need to tip the cart body over, can cause safety accidents, resulting in injuries to construction workers caused by the cart body.

[0051] Based on this, in order to solve the above technical problems, this embodiment provides a concrete transport cart, please refer to Figure 1-Figure 3 , comprising: a car 1, a rope retraction assembly 4, a baffle 2, and a locking pin assembly 3. The car 1 is an open design, with all four sides welded together by panels. The bottom has a slope along the direction of concrete transportation. This slope is mainly used to facilitate the subsequent flow of wastewater from cleaning the car 1 along the slope to the baffle 2. Two rope retraction assemblies 4 are provided, which are fixed to both sides of the car 1 by fasteners such as bolts and mounting plates, and the joints are sealed. The rope retraction assembly 4 is arranged adjacent to the direction of concrete transportation. A rope 43 is installed in the rope retraction assembly 4, which can drive the rope 43 for retraction and extension. In this embodiment, the rope 43 is mainly a steel wire rope. One end of the baffle 2 is hinged to the panel of the car 1. Specifically, the baffle 2 is arranged adjacent to the rope retraction assembly 4. An outflow port is opened on the side of the car 1 opposite to the baffle 2. A sealing rubber ring is provided at the outflow port. When the baffle 2 covers the outflow port, it can prevent concrete or water from flowing out. In addition, the locking pin assembly 3 is respectively installed on the baffle 2 and the panel of the outflow port for opening and closing the baffle 2 .

[0052] In this embodiment, when cleaning the carriage 1, the construction worker opens the baffle 2, and wastewater flows out of the outflow outlet under the guidance of the slope. This eliminates the need for the construction worker to flip the carriage 1 over to drain the cleaned wastewater, saving time and effort. Furthermore, the slope and baffle 2 cooperate with each other, allowing concrete to flow out of the outflow outlet during pouring, making it easier for construction workers to transfer the concrete.

[0053] In some embodiments, reference Figure 4The lock pin assembly 3 comprises a fixing base 31, a latch base 32, and a resilient latch. The fixing base 31 is fixedly mounted on the baffle 2 and has a socket. The latch base 32 is fixedly mounted on the outlet panel and has a pin hole. The resilient latch passes through the socket and the pin hole. When the resilient latch is separated from the socket, the baffle 2 is opened. The resilient latch allows for repeated use, thereby improving the stability and reliability of the lock pin assembly 3.

[0054] In this embodiment, the elastic latch comprises a latch member 33 and a spring 34. The latch member 33 extends through the fixing base 31 and the latch base 32 via a socket and a pin hole. A limit pin is mounted on the end of the latch member 33 facing the fixing base 31. The spring 34 is wound around the latch member 33 and restrained by the limit pin. It is also located on the latch base 32. A construction worker pulls on one end of the latch member 33, causing it to compress the spring 34, thereby separating the latch member 33 from the socket in the fixing base 31 and allowing the damper 2 to open. Conversely, when the construction worker releases the latch member 33, the spring 34 automatically returns the latch member 33 to the socket in the fixing base 31, locking the damper 2 to the outlet panel after closing it.

[0055] In this embodiment, when the rope retractor assembly 4 releases the rope 43, the head of the rope 43 can hook onto the crane's hook, allowing the cart to be lifted with the crane. When lifting is no longer required, the rope retractor assembly 4 can retract the rope 43, thereby preventing construction workers from loading concrete into the carriage 1 with a shovel. During the concrete transportation process, the baffle 2 is locked in place by the locking pin assembly 3, preventing it from separating from the side panel of the carriage 1, thereby preventing concrete from flowing out through the baffle 2. When the carriage 1 needs to be cleaned, the locking pin assembly 3 is opened, allowing the baffle 2 to open and close, and the cleaned wastewater can flow out from the opening between the baffle 2 and the carriage 1 panel.

[0056] In some embodiments, reference Figure 2The rope retraction assembly 4 comprises a housing 41, a rotating shaft 42, a rope 43, and a partition 44. The housing 41 is fixed to one side of the carriage 1 and has a hinged cover. The hinged cover is hingedly connected to the housing 41, and a lock is installed between the hinged cover and the housing 41. The rotating shaft 42 is mounted inside the housing 41 perpendicular to the direction in which the rope 43 is retracted and extended, and rotates relative to the housing 41. One end of the rotating shaft 42 extends to the outer end of the housing 41, and a handwheel 45 is fixedly connected to the extended end. One end of the rope 43 is fixed to the rotating shaft 42 and is wound around the rotating shaft 42 in a circumferential direction. The head of the rope 43 is provided with a hanging portion 431. Construction workers can retract and extend the rope 43 by turning the handwheel 45. The partition 44 is fixed inside the housing 41 and arranged parallel to the rotating shaft 42. The partition 44 has an inlet and outlet, through which the rope 43 passes, and the hanging portion 431 is restrained by the inlet and outlet. The hinged cover can be flipped over. When the rope 43 is not in use, the hinged cover covers the box 41, preventing concrete from entering the box 41 and ensuring that the components inside the box 41 are not affected. The isolation plate 44 can not only limit the hanging portion 431 of the rope 43 from entering the rotating shaft 42, but also further prevent concrete particles from entering the area near the rotating shaft 42.

[0057] In some embodiments, reference Figure 5 A lifting lug 5 is removably mounted on one side of the carriage 1 adjacent to the housing 41 via bolts or other fasteners. A housing 411 is provided within the housing 41, within which a balancing rope 6 is placed. The balancing rope 6 is used to connect to the crane's hook to balance the carriage 1. When construction workers use the crane's hook to lift the carriage 1, because the existing carriage 1 is only stressed at two ends, the cart is prone to tilting or shaking during the upward lifting process, causing concrete to fall and easily injuring nearby construction workers. Therefore, by providing a balancing rope 6, forces can be applied to the carriage 1 in all four directions, achieving force balance and effectively reducing the possibility of the cart tilting or shaking. Furthermore, construction workers can use the lifting lug 5 to assist the cart in changing direction. When the cart enters a relatively narrow space and cannot be turned by the handle, two to six construction workers can insert a crowbar into the lifting lug 5 and then lift the crowbar to change the cart's direction.

[0058] In some embodiments, reference Figure 9 A limiting groove 51 is provided in the middle of the lifting lug 5 for limiting the balance rope 6. The limiting groove 51 can limit the displacement of the balance rope 6, thereby further reducing the shaking or tilting of the cart during the lifting process.

[0059] More specifically, see Figure 8The balance rope 6 has an annular fixing portion 61 at each end, and the annular fixing portion 61 at one end can pass through the annular area of ​​the annular fixing portion 61 at the other end. When the balance rope 6 is used, it can be passed through the lifting eye 5 and then the small diameter end is passed through the large diameter end to lock the lifting eye 5. The large diameter end is then inserted into the crane hook for lifting. Figure 8 In order to save space, only the structural schematic diagram of the balance rope 6 is drawn, and the wavy line indicates that it can be extended infinitely. The balance ropes 6 at the left and right ends are connected together to form a complete balance rope 6, wherein the annular area formed by the annular fixing part 61 at the left end is larger than the annular area formed by the annular fixing part 61 at the right end.

[0060] Based on the above embodiment, to facilitate storage of the balance rope 6 and prevent loss of the balance rope 6, this solution provides a sliding storage box 7 for storing the balance rope 6. A slide 412 is provided on the inner wall of the box 41, and the storage box 7 is located within the storage cavity 411. The storage box 7 is slidably connected to the slide 412, and the balance rope 6 is placed in the storage box 7.

[0061] It should be noted that the lengths of the balance rope 6 and the rope 43 in this embodiment can both meet the lengths required for lifting.

[0062] In this device, when the rope retracting assembly 4 releases the rope 43, the head of the rope 43 can hook onto the crane's hook, allowing the cart to be lifted along with the crane. When lifting is no longer required, the rope retracting assembly 4 can retract the rope 43, thereby not interfering with the construction workers loading concrete into the carriage 1 with a shovel. During the concrete transportation process, the baffle 2 is locked in place by the locking pin assembly 3 and cannot be separated from the side panel of the carriage 1, thereby ensuring that the concrete does not flow out through the baffle 2. When the carriage 1 needs to be cleaned, the locking pin assembly 3 is opened, allowing the baffle 2 to be opened and closed, and the cleaned wastewater can flow out from the opening between the baffle 2 and the carriage 1 panel.

[0063] The above is only for explaining the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention without creative work should be included in the scope of protection of the present invention.
