Description

Technical Field

[0001] The utility model relates to the technical field of strength detection of electric power fittings, and particularly relates to a device for detecting the strength of electric power fittings. Background Art

[0002] An overhead line mainly refers to an overhead open wire, which is erected above the ground. It is a power transmission line that uses insulators to fix the transmission wire on a pole standing upright on the ground to transmit electric energy. It is relatively convenient for erection and maintenance, and has a low cost. The main components of an overhead line include: conductors and lightning conductors, poles, insulators, electric power fittings, pole foundations, guy wires and earthing devices, etc. The U-shaped hanging ring is one of the electric power fittings, and tensile tests need to be carried out on the U-shaped hanging ring during production.

[0003] In the prior art, when carrying out a tensile test on a U-shaped hanging ring, it is necessary to sequentially carry out the tensile test on the U-shaped hanging ring. To save time, two U-shaped hanging rings are sleeved in an arc shape and then stretched. Two U-shaped hanging rings can be stretched and tested at a time, improving work efficiency.

[0004] However, there are still certain problems when using the above operation method: when connecting and disassembling two U-shaped hanging rings, the disassembly and assembly between the U-shaped hanging rings still take a lot of time, thus affecting the test efficiency of the U-shaped hanging ring. Moreover, whether using a single U-shaped hanging ring test or a simultaneous test after sleeving two U-shaped hanging rings, during a single test process, it is necessary to load the mechanical damage load of the U-shaped hanging ring and then maintain it for 60 seconds, then measure the permanent deformation amount, then load the nominal failure load of the U-shaped hanging ring and maintain it for 60 seconds, and then continue to increase the load until the U-shaped hanging ring is damaged. The overall test time is usually about 3 minutes, and the time for maintaining the load accounts for most of the total time. During this period, the staff usually cannot carry out other work and can only wait, greatly wasting the time of the staff. Content of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a device for detecting the strength of electric power fittings capable of automatic loading and unloading, solving the problem that in the prior art, manual loading and unloading by personnel is required for each detection, resulting in waste of the time of the staff.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A strength detection device for electric power fittings, comprising a test bench, on which a first stretching roller is arranged and a long strip-shaped avoidance hole is opened. A stretching mechanism is arranged at the bottom of the test bench. The stretching mechanism comprises a second stretching roller, the upper end of the second stretching roller passes through the avoidance hole and the second stretching roller can reciprocate along the length direction of the avoidance hole. The detection device further comprises a feeding mechanism and a discharging mechanism. The feeding mechanism comprises a storage tank, and a through hole is opened in the storage tank in the vertical direction. The storage tank is fixedly arranged on the test bench and the lower end surface of the storage tank is located above the upper end surface of the first stretching roller. The discharging mechanism comprises a lifting unit and a discharging plate. The discharging plate is located above the test bench. The lower end of the lifting unit is fixedly arranged on the test bench and the upper end is connected to the discharging plate. A discharging unit is arranged on the discharging plate, and the discharging unit can push the electric power fitting to be tested. By arranging the feeding mechanism and the discharging mechanism, a batch of electric power fittings to be tested can be placed in the feeding mechanism. Subsequently, after the stretching detection by the stretching mechanism is completed, the discharging mechanism discharges the stretched electric power fittings. Then the feeding mechanism feeds again. After the staff adds materials, there is no need to complete manual discharging and material changing. During the detection process, the staff can leave the test bench to do other work, avoiding the problem of wasting the staff's time caused by manual feeding and discharging during each detection.

[0008] Preferably, the feeding mechanism further comprises fixing plates. There are two fixing plates, which are symmetrically arranged on both sides of the storage tank. The lower ends of the fixing plates are arranged on the test bench, and the upper ends of the fixing plates are fixedly connected to the storage tank. By arranging the fixing plates, while fixing the storage tank, a large installation space can be provided for the discharging mechanism.

[0009] Preferably, a material distribution unit is further opened at the lower end of the storage tank. The material distribution unit can limit the retention and falling of the electric power fittings in the storage tank. By arranging the material distribution unit, it can ensure the feeding of a single electric power fitting during feeding, avoiding the situation of multiple electric power fittings being stacked for feeding, which may lead to inaccurate test results.

[0010] Preferably, the material distribution unit comprises a motor and a material distribution part. The motor is fixedly arranged on the storage tank, and the material distribution part is spirally arranged and connected to the output shaft of the motor. By arranging the motor and the material distribution part, when the motor rotates one circle during feeding, at the same time, the spiral material distribution part drives the electric power fittings in the spiral groove to descend a certain distance. When the lowest spiral groove rotates, the lowest electric power fitting breaks away from the material distribution part, and at this time, the feeding of a single electric power fitting is completed.

[0011] Preferably, there are two material distribution units, and the two material distribution units are symmetrically arranged on the opposite side surfaces of the storage tank. By arranging two material distribution units, the two ends of the electric power fitting can be released simultaneously, avoiding the situation that the electric power fitting rotates and cannot be sleeved on the first stretching roller and the second stretching roller according to the preset track due to too large time interval between the releases of the two ends.

[0012] Preferably, the blanking plate is further provided with a guide hole, which is sleeved on the first stretching roller. The guide hole can be used to guide the blanking plate when it is lifted or lowered.

[0013] Preferably, two lifting units are symmetrically arranged at both ends of the blanking plate, and the lifting units include a lifting cylinder, the lower end of the lifting cylinder is fixedly connected to the test bench, and the upper end of the lifting cylinder is fixedly connected to the blanking plate.

[0014] Preferably, the unloading unit comprises an unloading cylinder, one end of which is fixed on the unloading plate, and the other end of which is used to push the electrical fittings that have completed the test.

[0015] Preferably, the stretching mechanism includes a hydraulic cylinder, one end of which is fixed on the bottom surface of the test bench and the other end is connected to a slider, the upper end of the slider is fixed to the second stretching roller, and a guide rail is also provided on the bottom surface of the test bench, and the slider is slidably connected to the guide rail.

[0016] Preferably, a mounting frame is further provided on the bottom end surface of the test bench, and a laser rangefinder is provided on the mounting frame, and the laser rangefinder is used to detect the distance between the test bench and the slider.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are as follows: through the provision of a feeding mechanism and a discharging mechanism, the electric fittings to be tested can be placed in batches in the feeding mechanism, and then after the stretching test of the stretching mechanism is completed, the discharging mechanism will discharging the stretched electric fittings, and then the feeding mechanism will load the materials. After the staff has added the materials, there is no need to complete manual discharging and changing of materials. During the detection process, the staff can leave the test bench to do the rest of the work, avoiding the problem of manual discharging and discharging of materials by personnel during each detection, which wastes the staff's time. Through the provision of a fixed plate, a larger installation space can be provided for the discharging mechanism while fixing the storage tank. Through the provision of a dividing unit, the loading of a single electric fitting can be ensured during loading, avoiding the situation where multiple electric fittings are stacked and loaded, thereby causing inaccurate test results. Through the provision of a motor and a dividing piece, the motor can rotate one circle during loading, and at the same time, the spiral dividing piece drives the electric fittings in the spiral groove to descend a certain distance. When the lowest spiral groove rotates, the lowest electric fitting is separated from the dividing piece, and the loading of a single electric fitting is completed at this time. By setting up two material distribution units, both ends of the electric hardware can be released at the same time, avoiding the electric hardware being unable to rotate on the first stretching roller and the second stretching roller according to the preset trajectory due to the long time interval between the two ends. The guide holes can guide the blanking plate when it is raised or lowered. BRIEF DESCRIPTION OF THE DRAWINGS
