Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing equipment technology, and more specifically, it relates to a special equipment inspection and testing device. Background Technology
[0002] Special equipment refers to equipment such as pressure vessels, pressure pipelines, elevators, and lifting machinery used under specific conditions. Among them, lifting machinery is the most common type of special equipment. Its metal structural components, such as main beams, end beams, and outriggers, as well as parts such as hooks, pulley shafts, and drums, may frequently require the use of ultrasonic flaw detectors to inspect and detect internal welds, corrosion, and cracks after prolonged use. Existing ultrasonic flaw detectors generally consist of a flaw detector body, connecting cables, and a flaw detector head.
[0003] Based on the above, when using an ultrasonic flaw detector, the cables connecting the probe and the main body are often scattered. When it is necessary to change the detection location or move the flaw detector, the staff has to manually wrap these scattered cables to prevent them from falling to the ground and being accidentally stepped on or scratched by objects on the ground. After arriving at the new detection location, the previously wrapped cables need to be unwrapped and scattered again. This series of operations is relatively cumbersome and energy-consuming. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a special equipment inspection and testing device. This device solves the problem that, when using an ultrasonic flaw detector, the cables connecting the probe and the main body are often scattered and loose. When changing the testing location or moving the flaw detector, workers have to manually wind up these scattered cables to prevent them from falling to the ground and being accidentally stepped on or scratched by objects. Upon reaching the new testing location, the previously wound cables need to be unwound again. This series of operations is relatively cumbersome and time-consuming.
[0005] The purpose and effectiveness of this special equipment inspection and testing device are achieved by the following specific technical means:
[0006] A special equipment inspection and testing device, comprising a flaw detector body;
[0007] A carrying handle, which is hinged to the outside of the flaw detector body;
[0008] A storage compartment is located behind the main body of the flaw detector.
[0009] A transmission chamber, which is fixedly connected to the rear of the storage compartment;
[0010] A first drive shaft is rotatably connected to the storage compartment and the transmission chamber.
[0011] A winding roller, which is coaxially and fixedly connected to the outside of the first drive shaft;
[0012] An extendable storage assembly is disposed inside the storage compartment and the transmission chamber;
[0013] An anti-detachment component is installed at the bottom of the flaw detector body.
[0014] Furthermore, the elongated storage component includes:
[0015] A metal sheet, which is fixedly connected to the rear of the flaw detector body;
[0016] An adsorption magnet is fixedly connected to the front of the storage compartment.
[0017] Furthermore, the elongated storage component also includes:
[0018] The cable has its two ends wound around the outside of the winding roller, and its middle part is fixedly connected to the inside of the winding roller;
[0019] The connector is fixedly connected to the lower end of the cable;
[0020] The flaw detector head is fixedly connected to the upper end of the cable.
[0021] Furthermore, the elongated storage component also includes:
[0022] A limiting ratchet is coaxially and fixedly connected to the outside of the first drive shaft;
[0023] A limiting pawl is rotatably connected inside the transmission chamber and engages with a limiting ratchet.
[0024] Furthermore, the elongated storage component also includes:
[0025] A spiral spring, wherein the inner end of the spiral spring is coaxially fixedly connected to the rear end of the first transmission shaft, and the outer end of the spiral spring is fixedly connected to the interior of the transmission chamber.
[0026] A reset spring, the upper end of which is fixedly connected to the outer end of the limiting pawl, and the lower end of which is fixedly connected to the inside of the transmission chamber.
[0027] Furthermore, the anti-fall-off component includes:
[0028] The first connector is fixedly connected to the bottom of the flaw detector body, and a threaded groove is provided on the outer side of the first connector.
[0029] The second connector is sleeved on the outer side of the bottom of the connector and is threadedly connected to the first connector.
[0030] Compared with the prior art, the present invention has the following beneficial effects:
[0031] First, the storage compartment can be easily fixed by a metal plate and an adsorption magnet, and the entire device can be moved with one hand. When the cable is in use, the storage compartment is separated and the flaw detector is pulled, and the cable extends automatically. The ratchet and pawl mechanism prevents the cable from being retracted. After use, the limit pawl is pressed, and the cable is automatically and quickly retracted under the action of the spiral spring. The whole process simplifies the cable loading and unloading and improves work efficiency.
[0032] Secondly, after the connector is inserted into the bottom of the flaw detector body, the connector can be firmly fixed to the bottom of the flaw detector body by rotating the second connector that is threaded to the first connector. This design effectively prevents the connector from accidentally falling off the bottom of the flaw detector body when the cable is pulled to inspect the lifting machinery, ensuring the smooth progress of the inspection and testing process.
[0033] This utility model simplifies the cable winding and unwinding process by setting up an elongated storage component, thereby improving work efficiency. The storage compartment can be adsorbed onto the back of the flaw detector body, improving overall portability. The connector is firmly fixed to the flaw detector body by a threaded connection, preventing the cable from falling off when pulled. The overall design optimizes the stability of cable winding and unwinding and connection, improving operational convenience and safety. Attached Figure Description

Detailed Implementation
[0043] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0044] Example 1:
[0045] As attached Figure 1 To be continued Figure 7 As shown:
[0046] This utility model provides a special equipment inspection and testing device, including a flaw detector body 1;
[0047] Handle 101, the handle 101 is hinged to the outside of the flaw detector body 1;
[0048] Storage compartment 3 is located behind the flaw detector body 1;
[0049] Transmission chamber 302 is fixedly connected to the rear of storage compartment 3;
[0050] The first drive shaft 4 is rotatably connected to the storage compartment 3 and the transmission chamber 302.
[0051] The winding roller 401 is coaxially and fixedly connected to the outside of the first drive shaft 4.
[0052] An elongated storage component is installed inside the storage compartment 3 and the transmission chamber 302.
[0053] The elongated storage component includes:
[0054] Metal sheet 2 is fixedly connected to the rear of the flaw detector body 1;
[0055] The magnetic magnet 301 is fixedly connected to the front of the storage compartment 3. Its function is to easily fix the storage compartment 3 to the back of the metal sheet 2 through the magnetic attraction between the metal sheet 2 and the magnetic magnet 301.
[0056] The extendable storage component also includes:
[0057] Cable 5, with both ends of cable 5 wound around the outside of winding roller 401, and the middle part of cable 5 fixedly connected to the inside of winding roller 401;
[0058] Connector 501 is fixedly connected to the lower end of cable 5;
[0059] The flaw detector head 502 is fixedly connected to the upper end of the cable 5. Its function is to separate the storage compartment 3 from the rear of the flaw detector body 1. Then, by pulling the flaw detector head 502, both ends of the cable 5 wrapped around the outside of the winding roller 401 can be driven to extend outward at the same time. At the same time, the first drive shaft 4 and the winding roller 401 are driven to rotate.
[0060] The extendable storage component also includes:
[0061] A ratchet 402 is coaxially and fixedly connected to the outside of the first drive shaft 4.
[0062] The limiting pawl 6 is rotatably connected inside the transmission chamber 302. The limiting pawl 6 meshes with the limiting ratchet 402. The effect is that under the action of the ratchet and pawl transmission mechanism formed by the meshing of the limiting pawl 6 and the limiting ratchet 402, the first transmission shaft 4 can only rotate in one direction, so that the part of the cable 5 extending out of the storage compartment 3 will not be retracted, making it convenient for staff to use.
[0063] The extendable storage component also includes:
[0064] The inner end of the spiral spring 403 is coaxially fixedly connected to the rear end of the first transmission shaft 4, and the outer end of the spiral spring 403 is fixedly connected to the inside of the transmission chamber 302.
[0065] The upper end of the return spring 601 is fixedly connected to the outer end of the limiting pawl 6, and the lower end of the return spring 601 is fixedly connected to the inside of the transmission chamber 302. Its function is that when the cable 5 is pulled outward to drive the first transmission shaft 4 to rotate, the spiral spring 403 will tighten and press down the outer end of the limiting pawl 6, so that the limiting pawl 6 can disengage from the limiting pawl 6. Under the rebound action of the spiral spring 403, the first transmission shaft 4 and the winding roller 401 rotate in opposite directions, so that both ends of the cable 5 are retracted into the storage compartment 3. The outer end of the limiting pawl 6 is released, and under the rebound action of the return spring 601, the limiting pawl 6 and the limiting ratchet 402 are engaged again.
[0066] The specific usage and function of this embodiment are as follows:
[0067] The storage compartment 3 can be easily fixed behind the metal plate 2 by the magnetic attraction of the metal plate 2 and the adsorption magnet 301, so that the whole unit can be moved by simply lifting the handle 101 with one hand. When the cable 5 needs to be extended for use, the storage compartment 3 is first separated from the rear of the flaw detector body 1, and then the flaw detector head 502 is pulled, which can drive both ends of the cable 5 wound on the outside of the winding roller 401 to extend outward at the same time. At the same time, the first drive shaft 4 and the winding roller 401 are driven to rotate. Under the action of the ratchet and pawl transmission mechanism formed by the engagement of the limiting pawl 6 and the limiting ratchet 402, the first drive shaft 4... It can rotate in one direction, so that the part of the cable 5 extending out of the storage compartment 3 will not be retracted, making it convenient for staff to use; after use, pressing down on the outer end of the limiting pawl 6 will disengage the limiting pawl 6 from the limiting pawl 402, so that under the rebound action of the spiral spring 403, the first drive shaft 4 and the winding roller 401 rotate in opposite directions, so that both ends of the cable 5 are retracted into the storage compartment 3. After releasing the outer end of the limiting pawl 6, under the rebound action of the return spring 601, the limiting pawl 6 and the limiting ratchet 402 are re-engaged, and then the metal piece 2 can be attracted to the back of the adsorption magnet 301 again.
[0068] Example 2:
[0069] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 7 As shown, it also includes an anti-detachment component, which is located at the bottom of the flaw detector body 1.
[0070] The anti-fall-off components include:
[0071] The first connector 102 is fixedly connected to the bottom of the flaw detector body 1, and a threaded groove is provided on the outer side of the first connector 102.
[0072] The second connector 7 is sleeved on the outer side of the bottom of the connector 501, and the second connector 7 is threadedly connected to the first connector 102.
[0073] The specific usage and function of this embodiment are as follows:
[0074] The connection point between the bottom of the flaw detector body 1 and the connector 501 is located above the second connector 7. After inserting the connector 501 into the bottom of the flaw detector body 1, the second connector 7 is rotated, and the second connector 7 is threadedly connected to the first connector 102, so that the second connector 7 and the first connector 102 are tightly connected together. This can prevent the connector 501 from being accidentally pulled out from the bottom of the flaw detector body 1 when the cable 5 is pulled to inspect the lifting machinery.
