Description

Technical Field

[0001] This utility model relates to the field of concrete conveying, specifically a concrete conveying pipe support and fixing device. Background Technology

[0002] In concrete pouring construction, when using a pump truck to pour concrete slabs or floors, it is necessary to use concrete delivery pipe supports to stably support the outlet of the delivery pipe. However, existing concrete delivery pipe supports generally adopt an integrated fixed-height structure, and once the support height is formed, it cannot be adjusted according to the actual construction needs. In addition, the part of the existing concrete delivery pipe support that supports the concrete delivery pipe is a horizontal bar structure. During the process of conveying pressurized concrete, the concrete delivery pipe will sway on the horizontal bar, affecting the construction progress and operational safety. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a concrete conveying pipe support and fixing device.

[0004] The technical solution of this utility model is as follows: A concrete conveying pipe support and fixing device includes a base frame and two sets of support components arranged opposite to each other on its upper side. A pressure-bearing component is provided between the two support components. The support components include locking rods and vertical frames. The vertical frames have a number of locking holes spaced vertically in the middle. The locking rods are configured to be able to be inserted into any of the locking holes laterally. The pressure-bearing component includes two pressure-bearing rods arranged in a cross pattern. One end of the pressure-bearing rod is rotatably connected to the upper end of one of the vertical frames, and the other end is inclined downwards towards the other vertical frame and rests on the upper side of the locking rod.

[0005] As one implementation method, the vertical frame has a trapezoidal structure that is narrower at the top and wider at the bottom.

[0006] Furthermore, the vertical frame includes two support rods arranged at relative inclinations and an upper connecting rod located between their upper ends, with a connecting sleeve rotatably sleeved on the upper connecting rod at the upper end of the pressure rod.

[0007] Furthermore, the locking hole extends horizontally through the two support rods of the vertical frame, and after the locking rod is inserted, both ends extend outwards from the outside of the two support rods respectively.

[0008] Preferably, the length of the upper connecting rod is 1.1 to 1.5 times the sum of the outer diameters of the two bearing rods.

[0009] To improve structural strength, the base frame is a long rectangular frame structure. Both the vertical frame and the base frame are welded from multiple steel pipes. The locking rods are made of steel bars, and the bearing rods are made of steel pipes or steel bars. The steel bars and steel pipes can be selected from the waste materials in the construction environment for waste utilization.

[0010] To facilitate the smooth insertion of the locking rod and provide stable support for the pressure-bearing rod, the diameter of the locking hole is 1.0 to 1.5 times the outer diameter of the locking rod.

[0011] The beneficial effects of this utility model are that, through the cooperative structure of two sets of support components and cross bearing rods, the bearing height can be flexibly fixed by using locking holes of different heights and locking rods for insertion, effectively solving the problem that traditional fixed-height supports cannot adapt to different construction scenarios; in addition, the cross-arranged bearing rods can not only evenly transfer the load of the conveying pipe to the two sets of support components, improving the bearing stability, but also support the conveying pipe in the upper V-shaped area formed by the two cross bearing rods during use. This V-shaped structure can form a natural clamping and limiting of the conveying pipe, which can restrict the left and right swing of the conveying pipe, ensure its stable placement, and guarantee the construction progress and operation safety.

Detailed Implementation

[0013] Example 1 Combination Figures 1-4 This embodiment provides a concrete conveying pipe support and fixing device for achieving stable support and flexible adjustment of the support height of the concrete conveying pipe. The fixing device mainly includes a base frame 4, two sets of support components 1 and a pressure-bearing component 2.

[0014] The base frame 4 adopts a long rectangular frame structure, and its size can be flexibly designed according to the laying span of the conveying pipe in the construction scenario. Under normal circumstances, the length of the base frame 4 is 1.2m-1.8m and the width is 0.3m-0.5m, which can not only ensure the installation spacing requirements of the support component 1, but also improve the overall stability of the device through a larger grounding area.

[0015] Specifically, the base frame 4 is made of multiple steel pipes welded together. Specifically, it is formed by two parallel longitudinal steel pipes and two parallel transverse steel pipes enclosing a closed frame. Seamless steel pipes with a diameter of 20-30mm are selected as raw materials. All welds are treated with full welding process to effectively ensure the connection strength and avoid the problems of detachment and deformation after long-term bearing of the conveying pipe and the concrete load inside the pipe.

[0016] Combination Figure 4 Two sets of support components 1 are symmetrically arranged at both ends of the upper side of the base frame 4. Preferably, the structures of the two sets of support components 1 are completely identical, and each set of support components 1 includes a vertical frame and a locking rod 3. The vertical frame has several locking holes 111 vertically spaced in the middle. The locking rod 3 is configured to be able to be horizontally inserted into any of the locking holes 111. One end of the pressure rod 21 is rotatably connected to the upper end of one of the vertical frames, and the other end is inclined downwards pointing towards the other vertical frame and resting on the upper side of the locking rod 3. In addition, the pressure rod 21 may also have several through holes spaced along its length. The locking rod 3 may also be configured to pass through both the locking holes 111 and the through holes of the pressure rod 21 to fix the pressure rod 21. This embodiment also requires machining through holes in the pressure rod 21. The implementation method can be selected as needed.

[0017] The vertical frame has a trapezoidal structure that is narrower at the top and wider at the bottom. This structure can effectively distribute the load transmitted by the pressure-bearing component 2, improve the anti-tilting ability of the vertical frame, and adapt to the radial pressure and axial thrust during the concrete conveying process.

[0018] Specifically, the vertical frame includes two relatively inclined support rods 11 and an upper connecting rod 12 connecting the upper ends of the two support rods 11. Both are made of seamless steel pipe with a diameter of 20-30mm, and the welding is a full weld. The lower ends of the two support rods 11 are welded and fixed to the upper surface of the base frame 4 at the four corners, ensuring that the force of the support assembly 1 is evenly transmitted to the base frame 4. The two ends of the upper connecting rod 12 are welded to the upper ends of the two support rods 11 respectively, forming a complete trapezoidal vertical frame. The length of the upper connecting rod 12 is designed to be... The sum of the outer diameters of the two bearing rods 21 is 1.1 to 1.5 times, which can provide sufficient rotation space for the bearing rods 21 and avoid excessive displacement gaps in the bearing rods 21 along the length of the upper connecting rod 12. At the same time, the locking holes 111 pass through the two support rods 11 of the vertical frame in the horizontal direction. After the locking rod 3 is inserted, its two ends extend out of the outside of the two support rods 11 respectively. The spacing of several locking holes 111 can be set to 50-100mm according to the height adjustment accuracy. The smaller the spacing, the higher the adjustment accuracy, which can adapt to more construction height requirements.

[0019] The pressure-bearing component 2 is located between the two sets of support components 1 and is used to support the concrete conveying pipe. It includes two pressure-bearing rods 21 arranged in a cross pattern. The two pressure-bearing rods 21 cross to form a V-shaped support surface, which can effectively prevent the conveying pipe from shifting laterally during operation. The material of the pressure-bearing rods 21 can be steel pipe or steel bar. Steel pipe is suitable for scenarios with large loads, while steel bar is easier to carry and install. The specific material can be flexibly selected according to the actual construction needs.

[0020] Both bearing rods 21 are fixedly fitted with connecting sleeves 22 at their upper ends. The connecting sleeves 22 are long cylindrical structures with inner diameters that match the outer diameters of the upper connecting rods 12. They can be flexibly rotatably fitted around the outer ring of the upper connecting rods 12, allowing the bearing rods 21 to rotate freely around the upper connecting rods 12.

[0021] The locking rod 3 cooperates with the locking hole 111 of the support component 1 to fix the position of the pressure-bearing rod 21. It is made of steel bar material, with a diameter of 12-20mm according to the pressure requirements, and a length greater than the distance between the two support rods 11 in the same group. After being inserted into the locking hole 111, both ends can extend 50-100mm outward from the outside of the support rod 11, which is convenient for the operator to insert and remove for adjustment.

[0022] Corresponding to the size of the locking rod 3, the diameter of the locking hole 111 is set to 1.0 to 1.5 times the outer diameter of the locking rod 3. This ensures that the locking rod 3 can be smoothly inserted into the locking hole 111, while also reducing the gap after insertion, preventing the locking rod 3 from shaking, and ensuring that the pressure rod 21 is fixed and stable.

[0023] In actual construction scenarios, firstly, the base frame 4 is placed at the preset support position along the concrete delivery pipe laying path, ensuring that the base frame 4 is placed horizontally. If the construction ground is uneven, the level of the base frame 4 can be adjusted by laying pads to ensure that the overall force of the device is uniform. Then, based on the height difference between the pump truck outlet height and the concrete pouring surface, the required support height is determined. The operator rotates the two bearing rods 21 and adjusts their tilt angle so that the V-shaped support surface formed by the intersection of the two bearing rods 21 reaches the preset height. Then, the locking rod 3 is inserted into the locking hole 111 at the corresponding height, ensuring that the locking rod 3 completely penetrates the two support rods 11. At this time, the lower end of the bearing rod 21 rests on the locking rod 3. The position of the bearing rod 21 is fixed by the support of the locking rod 3, completing the height adjustment. Subsequently, the concrete delivery pipe is placed on the upper V-shaped support surface formed by the two bearing rods 21. The delivery pipe is in contact with the upper V-shaped support surface of the bearing rods 21. The V-shaped structure can also limit the left and right swing of the delivery pipe, ensuring that the delivery pipe is stable and reliable during the high-pressure delivery of concrete.

[0024] If the support height needs to be adjusted during construction, simply pull out the locking rod 3, rotate the bearing rod 21 to the new preset height, and then insert the locking rod 3 to complete the adjustment. The operation is convenient and efficient, without the need to disassemble the entire device, which greatly improves construction efficiency.
