Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a ground pump pipe shock absorbing device and a shock absorbing method thereof. Background Art

[0002] With the development of the construction industry, ground pumps are often used in the concrete pouring process. However, the ground pump pipes need to be laid in advance when using the ground pump. In the process of pumping concrete, the ground pump pipes will generate large impact and vibration loads, and at the same time generate a lot of noise pollution. This load often causes a certain degree of damage to the existing structure. In traditional construction practices, fasteners are used to limit the ground pump pipes, and then the fasteners are connected to the existing structure. This form only changes the direct contact between the ground pump pipe and the existing structure to indirect contact, but it cannot achieve a shock-absorbing effect. The vibration load of the ground pump pipe will still be transmitted to the existing mechanism through the fasteners and cause damage to the existing structure. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a ground pump pipe shock absorbing device and a shock absorbing method thereof. Double springs are sequentially arranged on the transmission path between the ground pump pipe and the existing structure. In the process of transmitting impact vibration, the kinetic energy generated by the impact vibration is absorbed by alternating deformation and resetting between the double springs, thereby avoiding damage to the existing structure.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is a ground pump pipe shock absorbing device, comprising:

[0005] A bottom plate for connecting to an existing structure, wherein a first sliding rod is vertically connected to the bottom plate;

[0007] a first shock absorbing spring, wherein the first shock absorbing spring is located in the installation box and one end of the first shock absorbing spring is connected to one end of the first sliding rod inserted in the installation box, and the other end of the first shock absorbing spring is connected to the inner bottom wall of the installation box;

[0008] A clamp for clamping the grounding pump pipe, the clamp is arranged in the horizontal direction and is located above the installation box, the bottom of the clamp is vertically connected to a second slide bar, the second slide bar is slidably inserted in the installation box and directly opposite to the first slide bar, and a second through hole for the second slide bar to be slidably inserted is opened on the top of the installation box;

[0009] A second shock-absorbing spring, the second shock-absorbing spring is located in the installation box and one end of the second shock-absorbing spring is connected to one end of the second slide rod inserted in the installation box, and the other end is connected to the inner top wall of the installation box. When the second spring and the first spring are in the reset state, the first slide rod and the second slide rod are spaced a certain distance apart.

[0010] A further improvement of the pump pipe shock absorbing device of the present invention is that the length of the first slide bar is adjustable, and the first slide bar comprises:

[0011] A screw rod, the screw rod is vertically connected to the top of the bottom plate;

[0012] A threaded sleeve, one end of which is threadedly connected to the screw rod, and the other end of which is inserted into the first through hole, and the first spring is connected to the threaded sleeve.

[0013] A further improvement of the pump pipe shock absorbing device of the present invention is that the bottom plate is connected to the existing structure via anchor bolts, and a third through hole for the anchor bolts to pass through is provided on the bottom plate.

[0014] A further improvement of the pump tube shock absorbing device of the present invention is that one end of the first sliding rod located in the installation box is connected to a first anti-slip plate, the diameter of the first anti-slip plate is larger than the aperture of the first through hole, the first spring is sleeved on the first sliding rod and one end is connected to the first anti-slip plate, and the other end is connected to the inner bottom wall of the installation box.

[0026] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] The pump pipe vibration reduction device and the vibration reduction method thereof of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figure 1-2 The ground pump pipe vibration reduction device comprises:

[0029] A base plate 1 for connecting to an existing structure, with a first sliding rod vertically connected to the base plate 1;

[0030] An installation box 3, the installation box 3 is located above the bottom plate 1 and is slidably sleeved on the first slide bar, and a first through hole for the first slide bar to be slidably inserted is opened at the bottom of the installation box 3;

[0031] A first damping spring, which is located in the installation box 3 and has one end connected to one end of the first slide bar inserted in the installation box 3, and the other end connected to the inner bottom wall of the installation box 3;

[0032] A clamp 11 for clamping the grounding pump tube 12, the clamp 11 is arranged in the horizontal direction and is located above the installation box 3, the bottom of the clamp 11 is vertically connected to a second slide bar 8, the second slide bar 8 is slidably inserted in the installation box 3 and is opposite to the first slide bar, and the top of the installation box 3 is provided with a second through hole for the second slide bar 8 to be slidably inserted;

[0033] A second shock-absorbing spring is located in the installation box 3 and one end of the second shock-absorbing spring is connected to one end of the second slide bar 8 inserted in the installation box 3, and the other end is connected to the inner top wall of the installation box 3. When the second spring 9 and the first spring 6 are in the reset state, the first slide bar and the second slide bar 8 are spaced a certain distance apart.

[0034] Specifically, during the damping process of the ground pump pipe damping device, the first sliding bar and the second sliding bar 8 are always spaced a certain distance apart.

[0035] By limiting the distance between the first slide bar and the second slide bar 8, it is ensured that when the second slide bar 8 and the installation box 3 move downward during the shock absorbing process, the second slide bar 8 does not contact the first slide bar, thereby ensuring the shock absorbing effect.

[0036] The shock absorption principle of the ground pump pipe shock absorption device is as follows: when the ground pump pipe 12 vibrates vertically, the ground pump pipe 12 will first transfer the vibration load to the clamp 11, and the clamp 11 will transfer the vibration load to the second slide bar 8, and the second slide bar 8 will transfer the vibration load to the second spring 9, and the second spring 9 will transfer the vibration load to the installation box 3, and the installation box 3 will transfer the vibration load to the first spring 6, and the first spring 6 will transfer the vibration load to the first slide bar, and the first slide bar will transfer the vibration load to the base plate 1, and the base plate 1 will then transfer the vibration load to the existing structure.

[0037] Taking the downward vibration of the ground pump pipe as an example, the ground pump pipe 12 drives the clamp 11 to move downward, the clamp 11 drives the second slide bar 8 to move downward, the second slide bar 8 stretches the second spring 8 downward, the second spring 8 drives the installation box 3 to move downward, the installation box 3 stretches the first spring 6 downward, and the first spring pulls the first slide bar downward, wherein during the stretching process of the first spring, the second spring 8 is in a reset state, and the kinetic energy generated by the impact vibration is absorbed by the alternating stretching and resetting of the first spring and the second spring 8.

[0038] By arranging the first spring 6 and the first slide bar in cooperation with the second spring 9 and the second slide bar 8, the transmission path of the vibration load of the ground pump pipe 12 is extended, and the vibration load is diluted, thereby improving the shock absorption effect.

[0039] Specifically, the inner circumference of the clamp 11 is connected with a rubber pad.

[0040] By connecting the rubber pad to the inner periphery of the clamp 11, the clamping effect on the ground pump pipe 12 is improved. When the ground pump pipe 12 first transmits the vibration load to the clamp 11, the rubber pad first cushions the vibration, further improving the vibration cushioning effect.

[0041] Preferably, the length of the first slide bar is adjustable, and the first slide bar comprises:

[0042] A screw rod 4, the screw rod 4 is vertically connected to the top of the base plate 1;

[0043] A threaded sleeve 5 , one end of which is threadedly connected to the screw rod 4 , and the other end of which is inserted into the first through hole. The first spring 6 is connected to the threaded sleeve 5 .

[0044] By adjusting the length of the first slide bar, the installation height of the ground pump pipe 12 can be adjusted easily. At the same time, it can also prevent the installation box 3 from colliding too close to the bottom plate 1 when vibrating up and down, thereby affecting the shock absorption effect.

[0045] Preferably, the base plate 1 is connected to the existing structure via anchor bolts 2 , and a third through hole for the anchor bolts 2 to pass through is provided on the base plate 1 .

[0046] Specifically, a shock-absorbing pad is sandwiched between the bottom plate 1 and the existing structure.

[0047] By providing the shock absorbing pad, the base plate 1 is prevented from being rigidly connected to the existing structure. When the vibration load is transmitted to the base plate 1, the base plate 1 transmits the vibration load to the shock absorbing pad, thereby preventing the vibration load from damaging the existing structure.

[0048] Preferably, one end of the first slide rod located in the installation box 3 is connected to a first anti-slip plate 7, the diameter of the first anti-slip plate 7 is larger than the aperture of the first through hole, the first spring 6 is sleeved on the first slide rod and one end is connected to the first anti-slip plate 7, and the other end is connected to the inner bottom wall of the installation box 3.

[0049] By providing the first anti-slip plate 7, it is prevented that the first slide bar falls out of the installation box 3 during shock absorption, thereby affecting the shock absorption effect.

[0050] Preferably, one end of the second slide rod 8 located in the installation box 3 is connected to a second anti-slip plate 10, the diameter of the second anti-slip plate 10 is larger than the aperture of the second through hole, and the second spring 9 is sleeved on the second slide rod 8 and one end is connected to the second anti-slip plate 10, and the other end is connected to the inner top wall of the installation box 3.

[0051] The second anti-slip plate 10 is provided to prevent the second slide bar 8 from slipping out of the installation box 3 during shock absorption, thereby affecting the shock absorption effect.

[0052] A method for reducing vibration of a ground pump pipe comprises the following steps:

[0053] Step 1: Provide the above-mentioned ground pump pipe shock absorbing device and install it in place;

[0054] Step 2: Clamp the ground pump pipe 12 to the clamp 11;

[0055] Step 3: Pump concrete to the ground pump pipe 12.
