TECHNICAL FIELD
[0001] The present application relates to the technical field of building, in particular to a concrete transfer machine. BACKGROUND
[0002] A large amount of concrete is used in building construction, and the concrete needs to be transported according to the construction site in the construction site, and a concrete transfer machine needs to be used to transport the concrete to the designated construction site, and sometimes even needs to be lifted to the high floor of the construction site according to the construction situation.
[0003] The current concrete transfer machine usually has a hopper fixedly arranged on the transfer machine and cannot be disassembled, and when the concrete is transported to the high floor, the transfer machine needs to be hoisted to the high floor as a whole, thereby increasing the hoisting load of the crane. CONTENT OF THE UTILITY MODEL
[0004] In view of the defects of the prior art, the present application provides a concrete transfer machine, which has the advantages of being capable of conveniently transporting concrete to a high place and land, and being capable of conveniently disassembling the hopper from the transfer machine for separate hoisting when transporting the concrete to a high place, without the need to hoist the transfer machine as a whole, thereby reducing the hoisting load of the crane, and solves the problem that the current concrete transfer machine usually has a hopper fixedly arranged on the transfer machine and cannot be disassembled, and when the concrete is transported to the high floor, the transfer machine needs to be hoisted to the high floor as a whole, thereby increasing the hoisting load of the crane.
[0005] In order to achieve the above-mentioned purpose of conveniently transporting concrete to a high place and land, and conveniently disassembling the hopper from the transfer machine for separate hoisting when transporting the concrete to a high place, without the need to hoist the transfer machine as a whole, thereby reducing the hoisting load of the crane, the present application provides the following technical scheme: a concrete transfer machine, comprising a base, one end of the top of the base is hingedly connected to one end of the bottom of a placing frame through a hinge frame, the other end of the bottom of the placing frame is hingedly connected to a hydraulic rod through a hinge frame, one end of the hydraulic rod is hingedly connected to the bottom of the base through a support frame, an upper and lower through groove is formed in the middle of the base, a hopper is placed in the inside of the placing frame, a limiting frame is arranged on the side surface of the hopper, a limiting block is inserted into the middle inner wall of the limiting frame, a positioning rod is arranged at one end of the limiting block, a fixed plate is arranged at one end of the positioning rod, a hinge rod is arranged on one side of the fixed plate, the hinge rod is rotatably arranged in the middle inner wall of a wrench, a sliding rod is arranged on the inside of one end of the wrench, a pull rod is arranged on the inside of the other end of the wrench, the middle outer surface of the sliding rod is slidingly arranged in the middle inner wall of a sliding frame, and the sliding frame is arranged on the side surface of the placing frame through a fixed block.
[0006] The above solution allows for convenient high-altitude and land-based transport of concrete by pulling down the lever, causing the wrench to swing and the sliding rod to slide within the sliding frame. This gradually moves the hinged rod away from the placement frame, pulling the limiting block out of the limiting frame and releasing the restriction on the hopper. During high-altitude transport, the hopper can be easily detached from the transport machine for individual hoisting, eliminating the need to lift the entire transport machine and reducing the lifting load on the crane.
[0007] Furthermore, a telescopic rod is provided on one side of the fixing plate, one end of the telescopic rod is located on one side of the placement frame, and a spring is provided inside the telescopic rod. One end of the spring is located on one end of the inner wall of the telescopic outer tube of the telescopic rod, and the other end of the spring is located on one end of the telescopic inner rod of the telescopic rod.
[0008] The above scheme uses a telescopic rod and spring to apply a tension force to the fixed plate, which in turn applies a push force to the limiting block via the positioning rod. This allows the limiting block to be stably inserted into the limiting frame to restrict the position of the hopper.
[0009] Furthermore, the outer surface of the middle part of the positioning rod is slidably disposed within the inner wall of the middle part of the positioning frame, and the bottom of the positioning frame is disposed on one side of the placement frame by a fixing bracket.
[0010] The above scheme fixes the trajectory of the positioning rod by sliding its outer surface in the middle of the positioning frame within the inner wall of the positioning frame, thereby fixing the trajectory of the fixed plate and improving the stability of the fixed plate and positioning rod during movement.
[0011] Furthermore, the lateral centerline of the sliding frame is lower than the axis of the hinge rod.
[0012] The above solution prevents the hinge rod from pushing the limit block back into the limit frame through the fixing plate and positioning rod when the slide rod slides to the top of the inner wall of the slide frame. When the slide rod slides to the top of the inner wall of the slide frame with the wrench, the position of the limit block can be positioned on the outside of the limit frame, so that the hopper can move upward smoothly.
[0013] Furthermore, the distance between the hinge rod and the slide rod, which are rotatably mounted on the inner wall of the middle part of the wrench, is less than the distance between the hinge rod and the pull rod.
[0014] The above solution reduces the force required to pull the lever, allowing for easier and less strenuous operation of the wrench via the lever.
[0015] Furthermore, two lifting ropes are provided on both sides of the top of the hopper, with the two ends of the two lifting ropes respectively located at the two ends of the top of the hopper.
[0016] With the above solution, the two lifting ropes allow for convenient and stable lifting of the hopper via the crane's hook.
[0017] Furthermore, two placement racks are provided on both sides of the hopper, and the placement racks are L-shaped.
[0018] The above solution allows for the storage of the lifting ropes, preventing them from getting tangled on the transfer machine and affecting their use.
[0019] Furthermore, four insert rods are provided at the four corners of the bottom of the hopper, and the four insert rods are respectively inserted into four insertion holes. The four insertion holes are opened at the four corners of the bottom of the inner wall of the placement frame, and the bottom edge of the insert rod is rounded.
[0020] The above method allows the hopper to be fixed in place within the placement frame by inserting the insert rod into the corresponding socket, thus improving the stability of the hopper within the placement frame. The chamfered edge of the bottom edge of the insert rod makes it easy to insert the insert rod into the socket.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This concrete transfer machine, by pulling down the lever, causes the wrench to swing, which in turn causes the slide rod to slide within the slide frame, gradually moving the hinged rod away from the placement frame. This causes the limiting block to be pulled out of the limiting frame, releasing the restriction on the hopper. This allows for convenient high-altitude and land-based transfer of concrete. When transferring concrete at height, the hopper can be easily detached from the transfer machine for individual hoisting, eliminating the need to lift the entire transfer machine and reducing the lifting load on the crane.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a concrete transfer machine includes a base 1. One end of the top of the base 1 is hinged to one end of the bottom of the placement frame 2 via a hinge frame. The other end of the bottom of the placement frame 2 is hinged to a hydraulic rod 15 via a hinge frame. One end of the hydraulic rod 15 is hinged to the bottom of the base 1 via a support frame. A through groove is opened in the middle of the base 1. A hopper 3 is placed inside the placement frame 2. A limit frame 4 is provided on the side of the hopper 3. A limit block 5 is inserted into the inner wall of the middle of the limit frame 4. A positioning rod 6 is provided at one end of the limit block 5. A fixing plate 7 is provided at one end of the positioning rod 6. A hinge rod 8 is provided on one side of the fixing plate 7. The outer surface of the middle of the hinge rod 8 is rotatably disposed in the inner wall of the middle of the wrench 9. A sliding rod 10 is provided on the inner side of one end of the wrench 9. A pull rod 20 is provided on the inner side of the other end of the wrench 9. The outer surface of the middle of the sliding rod 10 is slidably disposed in the inner wall of the middle of the sliding frame 11. One side of the sliding frame 11 is disposed on the side of the placement frame 2 via a fixing block.
[0034] Please see Figure 3 A telescopic rod 13 is provided on one side of the fixed plate 7. One end of the telescopic rod 13 is located on one side of the placement frame 2. A spring 14 is provided inside the telescopic rod 13. One end of the spring 14 is located on one end of the inner wall of the telescopic outer tube of the telescopic rod 13, and the other end of the spring 14 is located on one end of the telescopic inner rod of the telescopic rod 13. The telescopic rod 13 and the spring 14 can apply a pulling force to the fixed plate 7, so that the fixed plate 7 can apply a pushing force to the limiting block 5 through the positioning rod 6, thereby allowing the limiting block 5 to be stably inserted into the limiting frame 4 to limit the position of the hopper 3.
[0035] Please see Figure 1 and Figure 3The outer surface of the middle part of the positioning rod 6 is slidably disposed within the inner wall of the middle part of the positioning frame 12. The bottom of the positioning frame 12 is disposed on one side of the placement frame 2 through a fixing bracket. The trajectory of the positioning rod 6 can be fixed by sliding the outer surface of the middle part of the positioning rod 6 within the inner wall of the middle part of the positioning frame 12, thereby fixing the trajectory of the fixing plate 7 and improving the stability of the fixing plate 7 and the positioning rod 6 when they move.
[0036] Please see Figure 1 , Figure 2 and Figure 3 The horizontal centerline of the slide frame 11 is lower than the axis of the hinge rod 8. This prevents the hinge rod 8 from pushing the limit block 5 back into the limit frame 4 through the fixing plate 7 and the positioning rod 6 when the slide rod 10 slides to the top of the inner wall of the slide frame 11. When the slide rod 10 slides to the top of the inner wall of the slide frame 11 through the wrench 9, the position of the limit block 5 can be positioned on the outside of the limit frame 4, so that the hopper 3 can move upward smoothly.
[0037] Please see Figure 1 , Figure 2 and Figure 3 The distance between the hinge rod 8 and the slide rod 10, which are rotatably mounted on the inner wall of the middle part of the wrench 9, is smaller than the distance between the hinge rod 8 and the pull rod 20. This reduces the force required to pull the pull rod 20 and allows the wrench 9 to swing easily and effortlessly via the pull rod 20.
[0038] Please see Figure 1 , Figure 2 and Figure 3 Two lifting ropes 16 are provided on both sides of the top of the hopper 3. The two ends of the two lifting ropes 16 are respectively set at the two ends of the top of the hopper 3. The two lifting ropes 16 can be used to easily and stably lift the hopper 3 through the hook of the crane.
[0039] Please see Figure 1 , Figure 2 and Figure 3 Two placement racks 17 are provided on both sides of the hopper 3. The placement racks 17 are L-shaped and can be used to store the lifting ropes 16, preventing the lifting ropes 16 from getting tangled on the conveyor and affecting their use.
[0040] Please see Figure 5 , Figure 6 and Figure 7 Four insertion rods 18 are provided at the four corners of the bottom of the hopper 3. The four insertion rods 18 are respectively inserted into four insertion holes 19. The four insertion holes 19 are opened at the four corners of the bottom of the inner wall of the placement frame 2. The bottom edge of the insertion rod 18 is rounded. By inserting the insertion rod 18 into the corresponding insertion hole 19, the placement position of the hopper 3 in the placement frame 2 can be fixed, thereby improving the stability of the hopper 3 in the placement frame 2. The rounded bottom edge of the insertion rod 18 makes it easy to insert the insertion rod 18 into the insertion hole 19.
[0041] In this embodiment, a concrete transfer machine allows for convenient high-altitude and land-based transfer of concrete. By pulling down the lever 20, the wrench 9 swings, causing the slide bar 10 to slide within the slide frame 11. This gradually moves the hinged rod 8 away from the placement frame 2, pulling the limiting block 5 out of the limiting frame 4 and releasing the restriction on the hopper 3. During high-altitude transfer, the hopper 3 can be easily detached from the transfer machine for individual hoisting, eliminating the need to lift the entire transfer machine and reducing the lifting load on the crane.
[0042] The working principle of the above embodiment is as follows: The concrete to be transferred is loaded into the hopper 3. The transfer machine is moved to the designated location by the rotating wheels at the bottom of the base 1. When the concrete needs to be transferred to a higher position, the pull rods 20 on both sides of the placement frame 2 are pulled down, causing the wrench 9 to swing. This causes the sliding rod 10 to swing upward on the inner wall of the middle part of the sliding frame 11. When the sliding rod 10 swings upward on the inner wall of the sliding frame 11, the distance between the hinge rod 8 in the middle of the wrench 9 and the sliding rod 10 will push the hinge rod 8 to gradually move away from the placement frame 2. This causes the hinge rod 8 to slide through the fixing plate 7 and the outer surface of the middle part of the positioning rod 6 in the inner wall of the middle part of the positioning frame 12 until the outer surface of the middle part of the sliding rod 10 slides into the top of the inner wall of the middle part of the sliding frame 11. The positioning rod 6 pulls the limiting block 5 out of the limiting frame 4, releasing the restriction on the limiting frame 4, and thus releasing the restriction on the hopper 3. The two lifting ropes 16 are then hung on the hooks of the crane, and the crane is used for operation. Hoist the hopper 3 upwards, then move it upwards from the placement frame 2. Hoist the hopper 3 to a high floor and gradually lower it into the placement frame 2 from above. Insert the insertion rod 18 into the insertion hole 19 to install the hopper 3 in place within the placement frame 2. Pull the pull rod 20 upwards to swing the wrench 9, causing the sliding rod 10 to slide downwards along the inner wall of the sliding frame 11. When the sliding rod 10 slides below the horizontal plane of the hinge rod 8, it will gradually move the hinge rod 8 closer to the placement frame 2, pushing the limit block 5 into the limit frame 4 to fix the position of the hopper 3. Bend the hoisting rope 16 and insert it into the placement frame 17. When it is necessary to transfer the concrete on land, move the transfer machine to the designated transfer location. The hydraulic rod 15 starts to extend, pushing the placement frame 2 to lift, allowing the concrete in the hopper 3 to be poured into the designated location through the inclined end of the inner wall of the hopper 3.
