Description

Technical Field

[0001] The utility model relates to a detection device for water supply and drainage pipes, and is applicable to the technical field of pipe detection. Background Technique

[0002] Water supply and drainage pipes refer to pipes used for supplying drinking water and discharging sewage. The water supply pipes are responsible for transporting clean water from the water treatment plant to households, enterprises and public facilities, while the drainage pipes are responsible for discharging the used water and wastewater from buildings and facilities to the sewage treatment plant or other treatment facilities. Water supply and drainage pipes are a key infrastructure for carrying important liquids. If the strength of the pipe material is insufficient, accidents such as leakage or rupture may occur, posing a threat to personnel and the environment. Therefore, before the water supply and drainage pipes leave the factory, it is necessary to conduct strength detection on them.

[0003] During the detection process, a pendulum impact testing machine will be used. The pendulum impact testing machine is a device used to test the strength and impact resistance of pipe materials. It simulates the impact conditions that may be suffered during actual use by applying an impact force on the pipe. The existing pendulum impact testing machine consists of a machine body, a pendulum arm, a pendulum hammer and a pipe placement table, etc. The pipe will be cut into multiple small sections for detection. The small sections of the pipe are placed on the pipe placement table, and then the pendulum arm is released. The pendulum arm will drive the pendulum hammer to directly impact the small section of the pipe. By analogy, multiple sections of the pipe can be tested one by one, and finally the strength of the pipe can be measured according to the damage conditions of multiple sections of the pipe.

[0004] However, the working surface of the pipe placement table of the existing pendulum impact testing machine for pipe placement is a flat surface, and the pipe abuts against the outwardly protruding wall surface at the upper end of the pipe placement table. When the pendulum hammer freely falls and impacts the pipe, the pipe often rolls off the pipe placement table to the ground due to the reaction force of the impact. This may lead to inaccuracy of the test results because the energy of the pendulum hammer may not be completely transferred to the pipe, and the pipe may be additionally damaged during the rolling process, which may result in inaccurate strength test results of the pipe and inconvenient picking up of the pipe that has rolled to the ground. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: To solve the above technical problem, the utility model provides a detection device for water supply and drainage pipes.

[0006] The technical solution adopted by the utility model is: A detection device for water supply and drainage pipes, characterized by having:

[0007] A base;

[0008] A pipe clamping mechanism, installed on the base, capable of clamping the water supply and drainage pipes to be detected;

[0009] The hammering mechanism is installed on the base, and a pendulum hammer capable of hammering the water supply and drainage pipe on the pipe clamping mechanism is installed at the end of the hammering mechanism. In this way, when it is necessary to detect the water supply and drainage pipe, the water supply and drainage pipe is placed on the pipe clamping mechanism and clamped by the pipe clamping mechanism. When the hammering mechanism operates and hammers the water supply and drainage pipe, it can effectively prevent the water supply and drainage pipe from falling off the pipe clamping mechanism.

[0010] The pipe clamping mechanism has a bottom plate, a first square seat is installed on the bottom plate, a rotatable first double-headed screw is arranged in the first square seat, first sliders are installed at both ends of the first double-headed screw through thread fit, a first sliding groove matched with the first slider is made in the first square seat, the first slider is slidably matched with the first sliding groove, a first clamping plate capable of extending out of the square seat is installed on the first slider, the first double-headed screw is driven by a driving mechanism arranged on the first square seat, and a locking mechanism is arranged between the first double-headed screw and the first square seat. In this way, when the driving mechanism drives the first double-headed screw to rotate, under the action of the thread fit between the first double-headed screw and the first slider and the sliding fit between the first slider and the first sliding groove, the two first sliders move relatively or towards each other, and the two first clamping plates can clamp the water supply and drainage pipe when moving towards each other along with the two first sliders.

[0011] The end of the first double-headed screw extends out of the first square seat, and the driving mechanism has a handle installed at the end of the first double-headed screw. In this way, it is convenient for personnel to rotate the first double-headed screw by operating the handle.

[0012] The locking mechanism has a rubber ring sleeved on the first double-headed screw, and the rubber ring can move on the first double-headed screw to a position where it contacts the first square seat. In this way, when the driving mechanism drives the first double-headed screw to rotate, by moving the rubber ring on the first double-headed screw to a position where it does not contact the first square seat, there is no friction between the rubber ring and the first square seat at this time, and the first double-headed screw and the first square seat can rotate relative to each other; after the driving mechanism drives the first double-headed screw to rotate and clamp the water supply and drainage pipe, move the rubber ring on the first double-headed screw to a position where it contacts the first square seat, and the friction between the rubber ring and the first square seat can play a role in locking the relative rotation between the first double-headed screw and the first square seat.

[0013] An auxiliary clamping mechanism is installed on the bottom plate. The pipe clamping mechanism and the auxiliary clamping mechanism respectively clamp the two ends of the water supply and drainage pipe. The auxiliary clamping mechanism has a second square seat installed on the bottom plate. A rotatable second double-headed screw is arranged in the second square seat. Second sliders are installed at both ends of the second double-headed screw through threaded cooperation. Second chutes for cooperating with the second sliders are made in the second square seat. The second sliders are in sliding cooperation with the second chutes. Second clamping plates capable of extending outside the square seat are installed on the second sliders. A transmission mechanism is arranged between the first double-headed screw and the second double-headed screw. In this way, during the process of the driving mechanism driving the first double-headed screw to rotate, the second double-headed screw can be driven to rotate synchronously under the action of the transmission mechanism, and the second clamping plates move on the second square seat along with the second sliders, so that the first clamping plates on the first square seat and the second clamping plates on the second square seat can clamp the two ends of the water supply and drainage pipe synchronously, playing a role in stably clamping the water supply and drainage pipe.

[0014] The end of the second double-headed screw extends outside the second square seat. The transmission mechanism has a driving gear installed on the first double-headed screw and a driven gear installed on the second double-headed screw. The driving gear and the driven gear are connected by a toothed belt. In this way, during the rotation of the first double-headed screw, the second double-headed screw is driven to rotate synchronously under the combined action of the driving gear, the toothed belt and the driven gear.

[0015] Mounting holes are made at the peripheral positions of the bottom plate. Bolts can be installed in the mounting holes. The bottom plate and the base are connected by bolts. In this way, it is convenient to stably install the bottom plate on the base by tightening the bolts, and at the same time, it is convenient to remove and replace the bottom plate from the base by unscrewing the bolts.

[0016] The hammering mechanism has a mounting seat installed on the base. A fixed shaft is installed on the mounting seat. A sleeve that can rotate relatively is sleeved on the fixed shaft. A connecting rod is installed on the sleeve. A pendulum hammer is installed on the connecting rod. In this way, after the water supply and drainage pipe is clamped on the pipe clamping mechanism, the pendulum hammer is moved upward and released, and the pendulum hammer will strike the water supply and drainage pipe under the action of its own weight.

[0017] Support columns are installed at the peripheral positions at the bottom of the base. Rubber pads are installed at the bottoms of the support columns.

[0018] The beneficial effects of the present utility model are as follows: By arranging a pipeline clamping mechanism on the base, the present utility model facilitates, after arranging the water supply and drainage pipeline on the base plate, rotating the first double-headed stud through the operating handle, and synchronously driving the first clamping plate in the first square seat and the second clamping plate in the second square seat to clamp both ends of the water supply and drainage pipeline under the action of the transmission mechanism, thereby realizing the stable clamping of the water supply and drainage pipeline on the base; By setting a hammering mechanism on the base, it is convenient for personnel to move the pendulum hammer upward and release it after clamping the water supply and drainage pipeline on the base plate, so that the pendulum hammer strikes the water supply and drainage pipeline under its own weight, facilitating the subsequent strength test of the water supply and drainage pipeline.

[0024] The present utility model will be further described in detail below in conjunction with the drawings and through embodiments. The following embodiments are explanations of the present utility model and the present utility model is not limited to the following embodiments.

[0025] This embodiment is a detection device for a water supply and drainage pipeline 6, which has a base 1 and a pipeline clamping mechanism 2 and a hammering mechanism 5 arranged on the base 1.

[0026] In this embodiment, support columns 1-1 are installed at the four surrounding positions of the bottom of the base 1, and rubber pads 1-2 are installed at the bottoms of the support columns 1-1. In this way, it is convenient to stably place the base 1 on the ground.

[0027] In this embodiment, a pipe clamping mechanism 2 is arranged on the base 1, which has a bottom plate 2-1. Mounting holes are made at the peripheral positions of the bottom plate 2-1, and bolts 2-8 can be installed in the mounting holes. The bottom plate 2-1 is installed on the base 1 through the bolts 2-8 installed in the mounting holes and is threadedly engaged with the base 1.

[0028] In this embodiment, a first square seat 2-2 is installed on the base 1. A rotatable first double-headed stud 2-3 is arranged in the first square seat 2-2. First sliders 2-4 are installed at both ends of the first double-headed stud 2-3 through threaded engagement. A first sliding groove 2-9 that cooperates with the first slider 2-4 is made in the first square seat 2-2. The first slider 2-4 is slidably engaged with the first sliding groove 2-9. A first clamping plate 2-5 that can extend out of the square seat is installed on the first slider 2-4. The end of the first double-headed stud 2-3 extends out of the first square seat 2-2, and a handle 2-6 is installed at the end of the first double-headed stud 2-3. In this way, after arranging the water supply and drainage pipe 6 on the pipe clamping mechanism 2, by operating the handle 2-6 and rotating the first double-headed stud 2-3, the two first sliders 2-4 move relatively or towards each other under the action of the threaded engagement between the first double-headed stud 2-3 and the first slider 2-4 and the sliding engagement between the first slider 2-4 and the first sliding groove 2-9. The two first clamping plates 2-5 can clamp the water supply and drainage pipe 6 during the process of moving towards each other along with the two first sliders 2-4.

[0029] Furthermore, a locking mechanism is arranged between the first double-headed stud 2-3 and the first square seat 2-2. The locking mechanism has a rubber ring 2-7 sleeved on the first double-headed stud 2-3, and the rubber ring 2-7 can move on the first double-headed stud 2-3 to a position where it contacts the first square seat 2-2. In this way, when the driving mechanism drives the first double-headed stud 2-3 to rotate, by moving the rubber ring 2-7 on the first double-headed stud 2-3 to a position where it does not contact the first square seat 2-2, there is no friction between the rubber ring 2-7 and the first square seat 2-2 at this time, and the first double-headed stud 2-3 and the first square seat 2-2 can rotate relative to each other; after the driving mechanism drives the first double-headed stud 2-3 to rotate and clamp the water supply and drainage pipe 6, move the rubber ring 2-7 on the first double-headed stud 2-3 to a position where it contacts the first square seat 2-2. The relative rotation between the first double-headed stud 2-3 and the first square seat 2-2 can be locked by the friction between the rubber ring 2-7 and the first square seat 2-2.

[0030] In this embodiment, an auxiliary clamping mechanism 3 is further provided on the bottom plate 2-1. The auxiliary clamping mechanism 3 has a second square seat 3-1 installed on the bottom plate 2-1. A rotatable second double-headed stud 3-2 is provided in the second square seat 3-1. Second sliders are installed at both ends of the second double-headed stud 3-2 by means of threaded engagement. Second chutes that cooperate with the second sliders are formed in the second square seat 3-1. The second sliders are in sliding fit with the second chutes. Second clamping plates 3-3 that can extend outside the square seat are installed on the second sliders. The end of the second double-headed stud 3-2 extends outside the second square seat 3-1.

[0031] In this embodiment, a transmission mechanism 4 is provided between the first double-headed stud 2-3 and the second double-headed stud 3-2. An active gear 4-1 is sleeved on the first double-headed stud 2-3. A driven gear 4-2 is sleeved on the second double-headed stud 3-2. A toothed belt 4-3 is connected between the active gear 4-1 and the driven gear 4-2. The thread helix directions at both ends of the first double-headed stud 2-3 and the second double-headed stud 3-2 are opposite. The thread helix directions at corresponding positions between the first double-headed stud 2-3 and the second double-headed stud 3-2 are opposite. Thus, when an operator operates the handle 2-6 to drive the first double-headed stud 2-3 to rotate, the second double-headed stud 3-2 can be driven to rotate synchronously under the action of the transmission mechanism 4. The two first clamping plates 2-5 on the first double-headed stud 2-3 and the two second clamping plates 3-3 on the second double-headed stud 3-2 are driven to move towards each other to clamp the water supply and drainage pipeline 6.

[0032] In this embodiment, the hammering mechanism 5 has a mounting seat 5-1 installed on the base 1. A fixed shaft 5-2 is installed on the mounting seat 5-1. A sleeve 5-3 that can rotate relatively is sleeved on the fixed shaft 5-2. A connecting rod 5-4 is installed on the sleeve 5-3. A pendulum hammer 5-5 is installed on the connecting rod 5-4. Thus, after an operator places the water supply and drainage pipeline 6 on the pipeline clamping mechanism 2 and the pipeline clamping mechanism 2 clamps the water supply and drainage pipeline 6, the operator moves the pendulum hammer 5-5 upward. After the operator releases the pendulum hammer 5-5, the pendulum hammer 5-5 will hammer the water supply and drainage pipeline 6 on the pipeline clamping mechanism 2 under its own weight, which is convenient for subsequent testing of the water supply and drainage pipeline 6.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
