A cable compressive strength testing device

Abstract

This utility model discloses a cable compression resistance testing device, relating to the field of cable compression resistance testing technology. It includes a testing platform body, a fixing frame, and a pressure plate. The fixing frame is welded to both sides of the top of the testing platform body, and an electric push rod is embedded in the center of the top of the fixing frame. When in use, the cable compression resistance testing device activates a drive motor, causing the guide plate to push the cable down from the load-bearing plate, thus automatically removing the tested cable. This eliminates the need for manual cable removal by operators and prevents operator injury from being crushed. It facilitates material retrieval and prevents injury from crushing. By allowing operators to wait until the storage box is full or encounter a defective cable before moving the storage box closer to the receiving box or fault box, the device eliminates the need to immediately classify and store cables based on the test results after each cable test. This facilitates classified storage during the use of the cable compression resistance testing device.

Description

Technical Field

[0001] This utility model relates to the field of cable compressive strength testing technology, specifically to a cable compressive strength testing device. Background Technology

[0002] The compressive strength of a cable refers to its ability to maintain its normal operating state when subjected to external pressure. The compressive strength of a cable mainly depends on factors such as its structural design and material selection. In order to test the compressive strength of a cable, a cable withstand voltage test is usually performed. The compressive strength test bench is a very common member of the cable compressive strength testing device, which is characterized by its compact structure.

[0003] According to patent number CN212008135U, a compressive strength testing device for cable production is disclosed. This utility model relates to the technical field of cable production, and in particular to a compressive strength testing device for cable production. It can conveniently test the compressive strength of cables, allowing technicians to easily understand the compressive strength of cables before burying them, thereby rationally arranging the cable burial route. The device includes a testing platform, four sets of support legs, two sets of support frames, two sets of crossbeams, a hydraulic device, a lifting rod, a connecting rod, a pressure plate, and a load-bearing plate. The tops of the four sets of support legs are respectively fixed to the left front side, right front side, left rear side, and right rear side of the bottom of the testing platform. The bottoms of the two sets of support frames are respectively fixed to the left and right sides of the top of the testing platform. The left and right ends of the two sets of crossbeams are respectively fixed to the top front and rear sides of the two sets of support frames. The bottom of the hydraulic device is fixed to the center of the top of the two sets of crossbeams. The lifting rod is located between the two sets of crossbeams.

[0004] However, during the use of the aforementioned patent, after the cable test is completed, the operator still needs to manually reach under the pressure plate to remove the tested cable. However, this method of material removal is cumbersome and poses a certain risk. When the lifting rod malfunctions and causes the pressure plate to descend rapidly, it can easily squeeze the operator's arm, leading to injury and affecting the use of the cable compressibility testing device.

[0005] To address the aforementioned issues, this application proposes a cable compressive strength testing device. Utility Model Content

[0006] The purpose of this invention is to provide a cable compressive strength testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable compressive strength testing device, comprising a testing platform body, a fixing frame and a pressure plate, wherein the fixing frame is welded to both sides of the top of the testing platform body, and an electric push rod is embedded in the middle of the top of the fixing frame, and the output end of the electric push rod is connected to the pressure plate, and a load-bearing plate is connected to the middle of the top of the testing platform body.

[0008] Preferably, a fixed seat is welded to the top of the main body of the testing platform near the load-bearing plate, and a guide rack is slidably connected inside the fixed seat. A fixed toothed plate is connected to the top of the fixed frame through a support plate.

[0009] Preferably, a guide plate is connected to one side of the outer wall of the guide rack, and a drive motor is connected to the top of the fixed rack.

[0010] Preferably, the output end of the drive motor is connected to a transmission rod, and the transmission rod is connected to a guide plate through a guide cavity.

[0011] Preferably, a gear is slidably connected to the bottom end of the guide plate, and a slide rail is connected to the side of the gear away from the guide plate, and the top end of the slide rail is welded to the fixed gear plate.

[0012] Preferably, a fixing plate is connected to the middle of the outer wall of the main body of the testing station, and a storage box is slidably connected to the top of the fixing plate.

[0013] Preferably, a limiting seat is welded to one side of the outer wall of the storage box, and a limiting post is slidably connected inside the limiting seat.

[0014] Preferably, a storage box is connected to one side of the bottom of the main body of the testing platform, and a fault box is connected to the side of the bottom of the main body of the testing platform away from the storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this cable compressive strength testing device, the drive motor is activated to push the cable off the load-bearing plate, thereby automatically removing the tested cable. This eliminates the need for operators to manually remove the cable and prevents operators from being crushed. It facilitates material retrieval and prevents crushing injuries. By allowing operators to wait until the storage box is full or encounter a defective cable before moving the storage box closer to the receiving box or fault box, the cable does not need to be immediately classified and stored according to the test results after each cable test. This facilitates classified storage when using the cable compressive strength testing device.

[0016] 1. During the cable production process, in order to promptly detect cable defects and potential hazards, the drive motor is first started to drive the transmission rod to rotate, causing the top of the guide plate to reciprocate along the fixed frame. This causes the gear to rotate along the fixed toothed plate. The rotation of the gear then causes the guide rack to move until the guide plate pushes the cable off the load-bearing plate. The tested cable is then automatically removed without the need for manual removal by the operator, and the operator does not need to put their hands under the pressure plate, thus preventing operator injury. Therefore, when using the cable compressive strength testing device, it facilitates material removal and prevents crushing injuries.

[0017] 2. During cable production, in order to promptly detect cable defects and potential problems, the storage box is first moved closer to the receiving box or fault box. At this time, the tested cables fall into the receiving box or fault box. This allows operators to wait until the storage box is full or encounter a defective cable before moving the storage box closer to the receiving box. Thus, it is not necessary to immediately classify and store cables according to the test results after each cable test. This facilitates the classification and storage when the cable compressive strength testing device is used. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a cable compressive strength testing device, comprising a testing platform body 1, a fixing frame 2, and a pressure plate 4. The fixing frame 2 is welded to both sides of the top of the testing platform body 1, and an electric push rod 3 is embedded in the middle of the top of the fixing frame 2. The output end of the electric push rod 3 is connected to the pressure plate 4. A load-bearing plate 5 is connected to the middle of the top of the testing platform body 1. A fixing seat 6 is welded to the side of the top of the testing platform body 1 near the load-bearing plate 5, and a guide rack 7 is slidably connected inside the fixing seat 6. A fixing toothed plate 9 is connected to the top of the fixing frame 2 via a support plate. A guide plate 8 is connected to one side of the outer wall of the rack 7, and a drive motor 10 is connected to the top of the fixed rack 9. A transmission rod 11 is connected to the output end of the drive motor 10, and the transmission rod 11 is connected to a guide plate 12 through a guide cavity. A gear 13 is slidably connected to the bottom end of the guide plate 12, and a slide rail 14 is connected to the side of the gear 13 away from the guide plate 12. The top end of the slide rail 14 is welded to the fixed rack 9. The gear 13 and the fixed rack 9 are meshed. The top end of the guide plate 12 is connected to the fixed frame 2 through a rotating seat. The guide rack 7 and the fixed rack 9 are parallel to each other.

[0030] In practice, during the cable production process, in order to detect cable defects and potential hazards in a timely manner, a pressure testing bench is needed to test the cable. In order to facilitate the operator to remove the tested cable and to prevent the operator from being crushed, the drive motor 10 is started first. Since the output end of the drive motor 10 is connected to the transmission rod 11, the drive motor 10 starts and drives the transmission rod 11 to rotate. Since the transmission rod 11 is connected to the guide plate 8 through the guide cavity, the rotation of the transmission rod 11 will generate a thrust on the guide plate 12, causing the top of the guide plate 12 to reciprocate along the fixed frame 2.

[0031] Furthermore, since the bottom end of the guide plate 12 is slidably connected to the gear 13, the rotation of the guide plate 12 drives the gear 13 to move along the slide rail 14. Since the top end of the gear 13 is meshed with the fixed tooth plate 9, the gear 13 rotates along the fixed tooth plate 9 when it moves. Since the bottom end of the gear 13 is meshed with the guide rack 7, the rotation of the gear 13 causes the guide rack 7 to move along the fixed seat 6. Since the guide rack 7 is welded to the guide plate 8, the movement of the guide rack 7 drives the guide plate 8 to move together.

[0032] Until the output plate 8 pushes the cable down the load-bearing plate 5, the output plate 8 will automatically return to its original position as the transmission rod 11 rotates continuously, and then automatically remove the tested cable. There is no need for the operator to manually remove the cable, and the operator does not need to put their palm under the pressure plate 4, thus preventing the operator from being crushed. Therefore, when using the cable compressibility testing device, it plays the role of facilitating material removal and preventing crushing injuries.

[0033] See Figures 1-3 , Figure 7 and Figure 8 It can be seen that a fixing plate 15 is connected to the middle of the outer wall of the main body 1 of the testing platform, and a storage box 16 is slidably connected to the top of the fixing plate 15; a limiting seat 17 is welded to one side of the outer wall of the storage box 16, and a limiting post 18 is slidably connected inside the limiting seat 17; a storage box 19 is connected to one side of the bottom of the main body 1 of the testing platform, and a fault box 20 is connected to the side of the bottom of the main body 1 of the testing platform away from the storage box 19; the two sides of the outer wall of the limiting post 18 are connected to the main body 1 of the testing platform, a through hole is opened at the bottom of the storage box 16, and an outlet cavity is opened on both sides of the outer wall of the fixing plate 15.

[0034] In practice, during the cable production process, in order to promptly detect cable defects and potential hazards, a pressure testing bench is needed to test the cables. To facilitate operators in quickly classifying the tested cables and thus improving work efficiency, after the tested cables enter the storage box 16, the storage box 16 is manually moved so that it moves horizontally along the fixed plate 15. Since the outer wall of the storage box 16 is in contact with the limiting seat 17, the limiting seat 17 slides along the limiting post 18, thereby guiding the movement of the storage box 16 until the storage box 16 moves above the receiving box 19 or the fault box 20.

[0035] Furthermore, since the storage box 16 has a through hole at its bottom and the fixing plate 15 has outlet cavities on both sides of its outer wall, the tested cables fall into the storage box 19 or the fault box 20 through the through hole and outlet cavities. Then, the operator can move the storage box 16 according to the test results. The storage box 16 can be moved closer to the storage box 19 only when it is full or when a defective cable is encountered. Thus, the cables can be classified and stored immediately according to the test results without having to test the cables once. This facilitates the classification and storage of cables when the cable compressive strength testing device is used.

[0036] In summary, when using this cable compressive strength testing device, the cable to be tested is first placed on the load-bearing plate 5 on the main body 1 of the testing platform. Then, the electric push rod 3 on the fixing frame 2 is activated, causing the pressure plate 4 to move down close to the load-bearing plate 5 until the pressure plate 4 is in contact with the cable, thereby testing the compressive strength of the cable. This is existing technology and will not be elaborated on here. By activating the drive motor 10, the guide plate 8 pushes the cable down from the load-bearing plate 5, thereby automatically removing the tested cable. There is no need for the operator to manually remove the cable, and it can prevent the operator from being crushed. By allowing the operator to wait until the storage box 16 is full or encounters a defective cable before moving the storage box 16 closer to the collection box 19 or the fault box 20, the cable does not need to be immediately classified and stored according to the test results after each cable test. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
