Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a pouring pipe supporting vehicle for concrete pouring. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, a pouring pipe is generally used to transport the concrete to the target area. At present, in order to reduce the labor intensity of construction workers, a support vehicle is usually used to support and move the pouring pipe.

[0003] The Chinese patent "A pouring pipe support device for concrete pouring" authorization announcement "CN220094974U" places the pouring pipe between the top frame and the bottom frame, and rotates the threaded rod to drive the contact head to move, which is conducive to the contact to clamp and fix the pouring pipes of different thicknesses for support.

[0004] In the above application, the casting pipe is fixed by rotating the threaded rod to push the contact head. However, when the casting pipe is casting concrete, concrete will splash around the casting pipe, causing part of the concrete to adhere to the threaded rod, making the surface of the threaded rod uneven and unable to be used normally. In addition, when the contact head is used to fix the casting pipe, the contact area with the casting pipe is small. When the casting pipe is pulled to move, the contact head and the casting pipe are likely to slide, resulting in a poor fixing effect.

[0005] Therefore, a pouring pipe supporting vehicle for concrete pouring is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a pouring pipe supporting vehicle for concrete pouring in order to solve the above-mentioned problem, which improves the problem that when the pouring pipe is pouring concrete, concrete splashes around the pouring pipe, causing part of the concrete to adhere to the threaded rod, making the surface of the threaded rod uneven and unable to be used normally, and the contact area between the contact head and the pouring pipe is small when the pouring pipe is fixed. When the pouring pipe is pulled to move, it is easy to cause the contact head and the pouring pipe to slide, resulting in a poor fixing effect.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a pouring pipe support vehicle for concrete pouring, comprising: a moving seat, a hydraulic jack is fixedly connected to the middle part of the top of the moving seat, a circular plate is installed on the top of the hydraulic jack, the top of the circular plate is rotatably connected to a first arc plate, one end of the first arc plate is hinged to a second arc plate, and a fixing mechanism is arranged on the top of the second arc plate; wherein, the fixing mechanism comprises a U-shaped plate fixedly connected to the upper end of the surface of the second arc plate, the inner wall of the U-shaped plate is fixedly connected to a cylinder, the inner wall of the cylinder is rotatably connected to a threaded rod, the surface of the threaded rod is threadedly connected to the moving plate, the bottom end of the moving plate is fixedly connected to two round rods, the bottom ends of the round rods pass through the cylinder, and a fixing component is arranged on the inner side of the second arc plate.

[0008] Preferably, the fixing assembly includes two limiting cylinders fixedly connected to the inner wall of the second arc-shaped plate, the inner wall of the limiting cylinder is slidably connected with a push rod, one end of the push rod passes through the limiting cylinder and is fixedly connected to the fixing plate, the bottom end of the round rod is fixedly connected to a U-shaped rod, both ends of the U-shaped rod are fixedly connected to push blocks, the push blocks are in the shape of a right triangle, and the other ends of the two push rods pass through the limiting cylinder and fit with the inclined surface of the corresponding push block. The two push rods are used to push the two fixing plates to move downward at the same time to contact and fix the casting pipe tightly, which is conducive to increasing the contact area when fixing the casting pipe and ensuring the stability of the casting pipe. At the same time, the two fixing plates are tilted downward from two directions to form a central force to fix the casting pipe tightly, which improves the fixing effect of the casting pipe, thereby ensuring the stability of the casting pipe during movement.

[0009] Preferably, a circular ring is fixedly connected to the surface of the push rod, the surface of the circular ring is slidably connected to the inner wall of the limiting cylinder, and a spring is fixedly connected between one end of the circular ring and the inner wall of the limiting cylinder. When the push block is driven to move upward to release the fixation of the casting pipe, the spring is conducive to the push rod driving the fixing plate to automatically reset to release the fixation of the casting pipe, and ensures that the other end of the push rod is always in contact with the inclined surface of the push block, which is conducive to the fixing operation of the fixing assembly again.

[0010] Preferably, a protective frame is fixedly connected to the top of the cylinder, and the shape of the protective frame is a flat-top cone, so as to prevent concrete from entering the cylinder and reduce the contact area between the cylinder and the cylinder during rotation and rotation, thereby reducing friction.

[0011] Preferably, two cleaning rings are fixedly connected to the bottom end of the cylinder, and the surfaces of the two round rods are slidably connected to the inner walls of the corresponding cleaning rings. When the round rod enters the cylinder, the cleaning rings are used to scrape away the concrete on the surface of the round rod, thereby preventing the concrete from entering the cylinder and affecting the threaded rod.

[0012] Preferably, the middle part of the fixing plate is concave in an arc shape, and a contact pad is fixedly connected to the inner wall of the fixing plate, which is conducive to better contact between the fixing plate and the surface of the casting pipe when fixing the casting pipe.

[0013] Preferably, the top end of the threaded rod passes through the cylinder and the protective frame in sequence and is fixedly connected with a turning knob, so that the staff can rotate the threaded rod conveniently and the rotation is labor-saving.

[0014] Preferably, both sides of the top of the movable seat form an angle with the horizontal plane, which is conducive to better dropping of impurities dropped on the movable seat.

[0015] The beneficial effects of the utility model are:

[0016] 1. By arranging the threaded rod inside the cylinder, the threaded rod is prevented from being exposed to the external environment, thereby preventing the concrete from adhering to the threaded rod when pouring concrete in the pouring pipe, thereby ensuring the normal use of the threaded rod. At the same time, when the threaded rod is rotated, the two push blocks are pushed downward at the same time under the action of the moving plate, the round rod and the U-shaped rod, so that the two push rods push the two fixed plates to move downward at the same time to contact and tightly fix the pouring pipe, which is beneficial to increase the contact area when fixing the pouring pipe and ensure the stability of the pouring pipe. At the same time, the two fixed plates tilt downward from two directions to form a central force to tightly fix the pouring pipe, thereby improving the fixing effect of the pouring pipe, thereby ensuring the stability of the pouring pipe during movement;

[0017] 2. When the push block is driven to move upward to release the fixation of the casting pipe, the spring helps the push rod to drive the fixing plate to automatically reset to release the fixation of the casting pipe, and ensures that the other end of the push rod is always in contact with the inclined surface of the push block, which is conducive to the fixing operation of the fixing component again.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a pouring pipe support vehicle for concrete pouring comprises: a moving seat 1, a hydraulic jack 2 is fixedly connected to the middle of the top of the moving seat 1, a circular plate 3 is installed on the top of the hydraulic jack 2, a first arc plate 4 is rotatably connected to the top of the circular plate 3, a second arc plate 5 is hinged at one end of the first arc plate 4, and a fixing mechanism 6 is arranged on the top of the second arc plate 5; wherein, the fixing mechanism 6 comprises a U-shaped plate 601 fixedly connected to the upper end of the surface of the second arc plate 5, a cylinder 602 is fixedly connected to the inner wall of the U-shaped plate 601, a threaded rod 603 is rotatably connected to the inner wall of the cylinder 602, a moving plate 604 is threadedly connected to the surface of the threaded rod 603, two round rods 605 are fixedly connected to the bottom end of the moving plate 604, the bottom end of the round rod 605 passes through the cylinder 602, and a fixing component 606 is arranged on the inner side of the second arc plate 5.

[0026] The other ends of the first arc plate 4 and the second arc plate 5 are fixedly connected to mounting plates, and the two mounting plates are fixed by threads. The hydraulic jack 2 is an existing publicly available technical field and will not be described in detail here. The circular plate 3 is installed with the piston rod of the hydraulic jack 2. The height of the circular plate 3 can be adjusted by the hydraulic jack 2, so that the horizontal height of the casting pipe can be adjusted by the first arc plate 4 and the second arc plate 5.

[0027] When fixing the casting pipe, first rotate the second arc plate 5, place the casting pipe on the first arc plate 4, and then rotate the second arc plate 5 to make the mounting plate at the other end of the second arc plate 5 fit with the mounting plate at the other end of the first arc plate 4, and connect the two mounting plates with bolts to fix the first arc plate 4 and the second arc plate 5. After completing this operation, drive the threaded rod 603 to rotate, so that the movable plate 604 drives the round rod 605 to move downward and drives the fixing assembly 606 to operate.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 606 includes two limiting cylinders 6061 fixedly connected to the inner wall of the second arc-shaped plate 5, the inner wall of the limiting cylinder 6061 is slidably connected with a push rod 6062, one end of the push rod 6062 passes through the limiting cylinder 6061 and is fixedly connected to the fixing plate 6063, the bottom end of the round rod 605 is fixedly connected with a U-shaped rod 6064, both ends of the U-shaped rod 6064 are fixedly connected with push blocks 6065, the shape of the push blocks 6065 is a right triangle, the other ends of the two push rods 6062 pass through the limiting cylinder 6061 and fit with the inclined surfaces of the corresponding push blocks 6065.

[0029] The two limiting cylinders 6061 are arranged at an angle, and the two limiting cylinders 6061 are symmetrical about the center of the second arc-shaped plate 5. The bottom ends of the two round rods 605 are fixedly connected to the middle part of the U-shaped rod 6064. When the round rod 605 moves downward, it pushes the U-shaped rod 6064 and the push block 6065 to move downward synchronously. When the push block 6065 moves downward, the push rod 6062 is pushed to move downward at an angle under the action of the inclined surface of the push block 6065, so that the two push rods 6062 push the two fixing plates 6063 to move downward at the same time to fit the surface of the casting pipe and fix the casting pipe.

[0030] like Figure 4 As shown, a circular ring 6066 is fixedly connected to the surface of the push rod 6062 , the surface of the circular ring 6066 is slidably connected to the inner wall of the limiting cylinder 6061 , and a spring 6067 is fixedly connected between one end of the circular ring 6066 and the inner wall of the limiting cylinder 6061 .

[0031] When the push rod 6062 moves, it will drive the ring 6066 to move synchronously and compress the spring 6067. When it is necessary to release the fixation of the casting pipe, the push block 6065 is driven to move upward. At this time, under the action of the spring 6067, the ring 6066 will be reset, thereby driving the push rod 6062 to automatically reset, so that the fixing plate 6063 releases the fixation of the casting pipe.

[0032] like Figure 3As shown, the top of the cylinder 602 is fixedly connected with a protection frame 6021, and the shape of the protection frame 6021 is a flat-top cone. The top of the threaded rod 603 passes through the cylinder 602 and the protection frame 6021 in sequence and is fixedly connected with a twist 608.

[0033] The bottom end of the knob 608 contacts the top end of the protection frame 6021. When the threaded rod 603 needs to be rotated, the knob 608 is simply rotated. The knob 608 is composed of a circular plate and three mounting rods.

[0034] like Figure 3 and Figure 5 As shown, two cleaning rings 607 are fixedly connected to the bottom end of the cylinder 602, and the surfaces of the two round rods 605 are slidably connected to the inner walls of the corresponding cleaning rings 607. The cleaning rings 607 are in the shape of a flat-top cone. When the casting pipe needs to be released, the threaded rod 603 is rotated in the reverse direction to drive the round rod 605 to move upward. At this time, the impurities adhering to the surface of the round rod 605 will be scraped off under the action of the cleaning rings 607.

[0035] like Figure 4 As shown, the middle part of the fixing plate 6063 is concave in an arc shape, and the inner wall of the fixing plate 6063 is fixedly connected with a contact pad 6068. When the fixing plate 6063 fixes the casting pipe, the surface of the contact pad 6068 contacts the surface of the casting pipe. The contact pad 6068 is made of rubber and can be deformed to a certain extent.

[0036] like Figure 1 As shown, both sides of the top of the moving seat 1 form an angle with the horizontal plane. Both sides of the top of the moving seat 1 are arranged to be inclined downward.

[0037] When the utility model is used, when fixing the pouring pipe, first rotate the second arc plate 5, place the pouring pipe on the first arc plate 4, and then rotate the second arc plate 5 to make the mounting plate at the other end of the second arc plate 5 fit with the mounting plate at the other end of the first arc plate 4, and use bolts to connect the two mounting plates, so as to fix the first arc plate 4 and the second arc plate 5. After completing this operation, rotate the knob 608 to drive the threaded rod 603 to rotate, so that the movable plate 604 drives the round rod 605 to move downward. When the rod 605 moves downward, it pushes the U-shaped rod 6064 and the push block 6065 to move downward synchronously. When the two push blocks 6065 move downward, the two push rods 6062 will be pushed to move downward at the same time under the action of the inclined surface of the push block 6065. At this time, the ring 6066 will be driven to move in the limiting cylinder 6061 and compress the spring 6067. When the two push rods 6062 move at the same time, they will push the two fixed plates 6063 to move downward at the same time to fit the surface of the casting pipe and tightly fix the casting pipe.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
