Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a vertical pump pipe fixing device. Background Technology

[0002] Ground pump pouring is widely used in domestic construction projects, especially for pouring large volumes of concrete. Indeed, while ground pump pouring has significant advantages in improving construction efficiency and meeting concrete pouring needs, it also faces some challenges in practical application, particularly in terms of pump pipe stability and pouring quality control.

[0003] During prolonged high-intensity use, pump pipes may sway or shift due to factors such as vibration, pressure changes, or insecure fixing devices. This instability not only affects construction efficiency but may also cause friction or collision between the pump pipe and the floor slab or supporting structure, further creating safety hazards. The instability and vibration of the pump pipe can lead to uneven concrete flow rate and discontinuous pouring, thereby affecting the uniformity, density, and final strength of the concrete. If the concrete is subjected to excessive vibration or compression during pouring, it may cause air bubbles to form or segregate, affecting the quality of the concrete.

[0004] In summary, if the pump pipe is not properly supported or not securely fixed, it may collide with the floor slab or other building structures during operation, leading to pipe damage and loosening of joints; prolonged friction may also cause damage to the floor slab and pump pipe. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a vertical pump pipe fixing device.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A vertical pump pipe fixing device, comprising:

[0008] A fixing frame, which is installed on the concrete floor slab using expansion bolts;

[0009] A pump pipe clamp is placed at the center of a fixed frame. Multiple rubber-metal spiral composite springs are installed between the pump pipe clamp and the fixed frame. The pump pipe clamp is clamped onto the pump pipe of the ground pump.

[0010] The fixed frame includes four angle steels arranged in a circular array. The four angle steels are of the same length and are welded end to end.

[0011] Two strip holes are respectively opened on the angle steel on the left and right sides of the fixing frame, and the expansion bolts pass through the strip holes.

[0012] The pump pipe jacket includes two symmetrical half-jackets, which are connected and fixed by bolts and nuts that engage with each other. Each of the two half-jackets has a semi-circular groove in the middle of its opposite side.

[0013] The diameter of the circle corresponding to the groove is 1-3 mm smaller than the outer diameter of the pump pipe.

[0014] The semi-jacket includes a semi-circular inner clamping plate, a U-shaped outer clamping plate, a rectangular connecting plate, and a rectangular supporting plate. The connecting plate is welded between the side ends of the inner clamping plate and the outer clamping plate, and the supporting plate is welded between the middle of the outer side of the inner clamping plate and the middle of the inner side of the outer clamping plate.

[0015] The fixed frame has a first spring limiting block fixed to the inner side facing the pump pipe clamp, and the pump pipe clamp has a second spring limiting block fixed to the outer side facing the fixed frame. The two ends of the rubber-metal spiral composite spring are respectively fitted onto the first spring limiting block and the second spring limiting block.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, a vertical pump pipe fixing device includes a fixing frame 1 and a pump pipe clamp 2.

[0026] The fixed frame 1 includes four angle steels 11 arranged in a circular array. The four angle steels 11 are of the same length and are welded end to end.

[0027] The fixing frame 1 is installed on the concrete floor slab 200 using expansion bolts 100. Specifically, two strip holes 111 are opened on the angle steel 11 on the left and right sides of the fixing frame 1, and the expansion bolts 100 pass through the strip holes 111. The tail of the expansion bolts 100 is installed in the mounting holes on the concrete floor slab 200.

[0028] The pump pipe jacket 2 includes two symmetrical half-jackets 21. The two half-jackets 21 are connected and fixed by bolts 22 and nuts 23 that are screwed together. Each of the two half-jackets 21 has a semi-circular groove 211 in the middle of one side facing each other.

[0029] The semi-jacket 21 includes a semi-circular inner clamping plate 212, a U-shaped outer clamping plate 213, a rectangular connecting plate 214, and a rectangular support plate 215. The connecting plate 214 is welded between the side ends of the inner clamping plate 212 and the outer clamping plate 213, and the support plate 215 is welded between the outer middle of the inner clamping plate 212 and the inner middle of the outer clamping plate 213.

[0030] A circular hole is provided on the connecting plate 214. The bolt 22 passes through the adjacent and connected circular holes on the two half-jackets 21 and is screwed into the nut 23, thereby assembling the two half-jackets 21 into a pump pipe jacket.

[0031] The pump pipe sleeve 2 is placed at the center of the fixed frame 1. Multiple rubber-metal spiral composite springs 3 are installed between the pump pipe sleeve 2 and the fixed frame 1. Specifically, a rubber-metal spiral composite spring 3 is installed between the middle of each half-sleeve 21 and the fixed frame 1, and a rubber-metal spiral composite spring 3 is installed between each of the two ends of each half-sleeve 21 and the fixed frame 1.

[0032] To prevent the rubber-metal spiral composite spring 3 from slipping between its two ends and the fixed frame 1 and the pump pipe clamp 2 due to vibration, a first spring limiting block 12 facing the pump pipe clamp is fixed to the inner side of the fixed frame 1, and a second spring limiting block 24 facing the fixed frame 1 is fixed to the outer side of the pump pipe clamp 2. The two ends of the rubber-metal spiral composite spring 3 are respectively fitted onto the first spring limiting block 12 and the second spring limiting block 24.

[0033] The pump pipe clamp 2 is clamped onto the ground pump pipe. Specifically, the ground pump pipe is clamped in the two clamping grooves 211 of the pump pipe clamp 2. In order to ensure that the pump pipe clamp 2 clamps the ground pump pipe tightly, in this embodiment, the diameter of the circle corresponding to the clamping groove 211 is 2 mm smaller than the outer diameter of the ground pump pipe.

[0034] In addition to the data used in this embodiment, the diameter of the circle corresponding to the groove 211 is 1 to 3 millimeters smaller than the outer diameter of the ground pump pipe, which is within this range.

[0035] The pump pipe is fixed by the fixed frame 1, the rubber-metal spiral composite spring 3, and the pump pipe clamp 2. The rubber-metal spiral composite spring 3 is used to reduce and buffer the vibration of the pump pipe during operation, and prevent the pump pipe from colliding with the floor slab or other building structures during operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
