Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment welding, and in particular relates to a crowbar device. Background Art

[0002] In the current manufacture of electrical high-voltage switchgear, it is necessary to weld the reinforcement ribs on the door panels to ensure the stability of the shape of the door panels. When welding the reinforcement ribs on the door panels, due to reasons such as manufacturing precision, there may be interference fit between the reinforcement ribs and the door panels, and the reinforcement ribs cannot be stably loaded onto the door panels for welding. It is necessary to use a crowbar to stabilize the reinforcement ribs before welding them.

[0003] In the prior art, when the reinforcement ribs are fixed and welded, a crowbar is used for fixing. Since the prying angle of the crowbar cannot be judged, if the prying angle of the crowbar is small, the reinforcement ribs are not in the specified position when the reinforcement ribs are welded, and the reinforcement ribs have a low stabilizing effect on the door panel. If the prying angle of the crowbar is large, the crowbar may exert a large force on the door panel, thereby causing damage to the door panel. Summary of the invention

[0004] The present application aims to at least to some extent solve the technical problem that the angle of a crowbar cannot be determined when welding reinforcing ribs. To this end, the present application provides a crowbar device.

[0005] A crowbar device provided in an embodiment of the present application includes a crowbar, wherein the crowbar includes a crowbar and a crowbar head connected to the crowbar, and further includes:

[0006] A data inclinometer is arranged on the crowbar to measure the inclination angle of the crowbar.

[0007] When welding the reinforcement ribs of the door panel of the electrical high-voltage switch cabinet, when the operator uses a crowbar device to fix the reinforcement ribs, since the crowbar is equipped with a data inclinometer, the inclination angle of the crowbar (i.e., the prying angle of the crowbar) can be quantified and observed through the data inclinometer, so that the operator can intuitively judge whether the prying angle of the crowbar device is appropriate, thereby avoiding the problem of the reinforcement ribs not being properly welded or the door panel being damaged due to the prying angle being too small or too large during the prying process.

[0008] In some embodiments, the crowbar device further comprises a support column, the crowbar has a crowbar, and the support column is arranged on the outer wall of the crowbar. This solution can increase the torque of the crowbar when fixing the reinforcing rib, and the crowbar device can fix the reinforcing rib when the prying angle of the crowbar device is small.

[0009] In some embodiments, the pry bar has a support end, and the data inclinometer is arranged at the support end. Through this solution, the operator can observe the data of the data inclinometer intuitively and clearly when fixing the reinforcing rib.

[0010] In some embodiments, the pry head is bent at the supporting end, and the bending angle of the pry head relative to the pry bar is 90-145 degrees.

[0011] In some embodiments, the pry head and the pry bar are detachably connected. The detachable connection facilitates replacement of the pry head or the pry bar when it is damaged, and the pry bar device can meet insertion requirements of different gaps by replacing pry heads of different thicknesses.

[0012] In some embodiments, the support column is detachably connected to the support end.

[0013] In some embodiments, a support pad is provided at one end of the support column away from the pry bar. The support pad can be provided to prevent the support column from damaging the door panel.

[0014] In some embodiments, the support pad is detachably connected to the support column.

[0015] In some embodiments, the crowbar device further includes an anti-slip sleeve, and the crowbar is further provided with a movable end arranged opposite to the supporting end, and the anti-slip sleeve is sleeved on the movable end.

[0016] In some embodiments, the pry bar further has a plurality of sub-connecting rods, and the plurality of sub-connecting rods are threadedly connected to each other in pairs, and the supporting end and the movable end are respectively arranged on the two sub-connecting rods located at the outermost ends.

[0017] In an embodiment of the present application, the prying device includes a pry bar, a pry head and a data inclinometer, wherein the data inclinometer is arranged in a groove of the pry bar, and the pry head is bent and arranged at one end of the pry bar. When the reinforcement rib is fixedly welded, the data inclinometer displays the angle between the pry bar and the door panel or the reinforcement rib in real time, so that the operator can intuitively observe the size of the angle between the pry bar and the door panel or the reinforcement rib, and then determine whether to continue prying the crowbar device or stop prying the crowbar device, thereby reducing the chance of damage to the door panel and the reinforcement rib.

[0034] When welding the reinforcing rib 600 of the door panel 200 of the electrical high-voltage switchgear, due to reasons such as manufacturing precision, there may be an interference fit between the reinforcing rib 600 and the door panel 200, and the reinforcing rib 600 cannot be stably loaded onto the door panel 200 for welding. It is necessary to use a crowbar 100 to stabilize the reinforcing rib 600 before welding the reinforcing rib 600.

[0035] In the related art, when the reinforcement 600 is fixed and welded, a crowbar 100 is used for fixing. Since the prying angle of the crowbar 100 cannot be determined, if the prying angle of the crowbar 100 is small, the reinforcement 600 is not in the specified position when the reinforcement 600 is welded, and the reinforcement 600 has a low stabilizing effect on the door panel 200. If the prying angle of the crowbar 100 is large, the crowbar 100 may exert a large force on the door panel 200, thereby causing damage to the door panel 200.

[0036] Based on this, the inventors found that in daily production, if the angle between the pry bar 110 and the door panel 200 or the reinforcement rib 600 can be displayed in real time, and then it can be determined whether the fixation of the reinforcement rib 600 meets the requirements, the risk of damage to the door panel 200 can be reduced, and the fixing welding efficiency of the reinforcement rib 600 can be improved.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0038] See also Figure 1-Figure 4The embodiment of the present application provides a prying device, including a crowbar 100 and a data inclinometer 300. The crowbar device provided in the embodiment of the present application is mainly used for fixing the reinforcing rib 600 when welding the reinforcing rib 600 of the door panel 200 of the electrical high-voltage switch cabinet, so that the position of the reinforcing rib 600 is stable when welding.

[0039] Among them, the crowbar 100 includes a crowbar 110 and a crow head 120. Specifically, the crowbar 110 can be in the shape of a cylinder or a rectangle. In the embodiment of the present application, the crowbar 110 is cylindrical, wherein the crowbar 110 has a groove 114. The shape of the groove 114 can be rectangular or circular. In the embodiment of the present application, the groove 114 is rectangular. Specifically, the groove 114 is arranged on the outer wall of the rod body of the crowbar 110 and is arranged along the axial direction of the crowbar 110. The two long sides of the groove 114 are parallel to the axis of the crowbar 110.

[0040] Among them, the pry bar 110 serves as the installation basis for the other components of the crowbar device. Specifically, the pry bar 110 can be made of metal materials such as high-carbon steel. The high-carbon steel has strong toughness and high temperature resistance, which can prevent the pry bar 110 from being damaged by high temperature when welding the reinforcement rib 600, thereby increasing the service life of the pry bar 110. At the same time, when fixing the reinforcement rib 600, the operator needs to use a larger force on the pry bar 110. At this time, the material of the pry bar 110 is high-carbon steel, which makes the pry bar 110 not easily damaged by a large force.

[0041] The pry head 120 is bent and arranged at one end of the pry bar 110. Specifically, the pry head 120 is flat, and one end of the pry head 120 matches the shape and size of the bottom surface of the pry bar 110 and is connected to the bottom surface of the pry bar 110. The thickness of the pry head 120 decreases successively from the end of the pry head 120 connected to the pry bar 110 to the end of the pry head 120 away from the pry bar 110 to form a flat structure, so that the pry head 120 can be inserted into a space with a small gap for work.

[0042] It should be understood that when the reinforcement 600 is fixed and welded, a crowbar 100 is used for fixing. Since the prying angle of the crowbar 100 cannot be quantified, the operator is required to judge the angle of the crowbar 100 based on experience. If the prying angle of the crowbar 100 is small, the reinforcement 600 is not in the specified position when the reinforcement 600 is welded, and the reinforcement 600 has a lower stabilizing effect on the door panel 200. If the prying angle of the crowbar 100 is large, the operator may use a larger force on the crowbar 100, resulting in a larger force of the crowbar 100 on the door panel 200, which makes the door panel 200 at risk of damage. At the same time, each time the reinforcement 600 is fixed and strengthened, the operator is required to spend time to judge the approximate prying angle based on experience, thereby reducing the fixing and welding efficiency of the reinforcement 600.

[0043] In order to improve the above-mentioned problem, a solution is provided in the implementation of the present application, wherein the data inclinometer 300 can be arranged on the surface of the pry bar 110 or embedded in the surface of the pry bar 110. In the embodiment of the present application, the data inclinometer 300 is arranged in the groove 114. The data inclinometer 300 is a prior art with mature technology, such as the German core digital display inclinometer TN-IP65. After determining the reference plane before use, the angle between the measured object and the reference plane can be displayed on the screen. Specifically, the data inclinometer 300 matches the shape of the groove 114 to measure the inclination angle of the pry bar 110 (that is, the angle between the pry bar 110 and the door panel 200 or the reinforcement rib 600). Specifically, according to usage habits or process requirements, the surface of the door panel 200 or the reinforcement rib 600 is set as the reference surface of the data inclinometer 300. Then, through experiments, it is determined that the data displayed by the data inclinometer 300 is sufficient to fix the reinforcement rib 600 without damaging the door panel 200 and record the data.

[0044] In some embodiments, see Figure 1-Figure 4 The crowbar device also includes a support column 400, and the crowbar 110 is provided with a support end 111, a movable end 112 and a prying plane 122, wherein the prying head 120 is bent and arranged at the support end 111, one end of the support column 400 is arranged at the support end 111 along a direction perpendicular to the axial direction of the crowbar 110, and the end of the support column 400 connected to the support end 111 faces the prying plane 122, specifically, the prying plane 122 and the end of the support column 400 connected to the support end 111 are both arranged away from the working plane, wherein the door panel One end of door panel 200 has a fixed end 210. When the reinforcing rib 600 is fixed, the prying plane 122 is inserted into the fixed end 210 of the door panel 200, and the prying plane 122 is against the fixed end 210. At this time, there is an angle between the pry bar 110 and the door panel 200, and the other end of the support column 400 is against the door panel 200 or the reinforcing rib 600, so that the torque of the pry bar 110 is increased, and a smaller force can be used to fix the reinforcing rib 600. At the same time, the support column 400 can also participate in the fixing of the reinforcing rib 600.

[0045] When welding the reinforcing ribs of the door panel 200, for example, the door panel 200 of the KYN28A-12 high-voltage switch cabinet, the upper end of the door panel 200 has a fixed end 210, wherein the pry head 120 is inserted into the fixed end 210, and the support column is against the door panel 200 or the reinforcing rib 600. When the bending angle of the pry head 120 relative to the rod body of the pry bar 110 is 90-180 degrees, specifically, the angle formed by the prying plane 122 and the plane where the element line located at the top of the outer wall of the pry bar 110 and away from the support column 400 is 90-145 degrees, the data recorded by the data inclinometer 300 is 10-15 degrees, and when the door panel 200 is welded, the pry head 120 is inserted into the fixed end 210, and the support column is against the door panel 200 or the reinforcing rib 600. When the pry head 120 is bent at an angle of 90-180 degrees relative to the rod body of the pry bar 110, specifically, the angle formed by the prying plane 122 and the plane where the element line located at the top of the outer wall of the pry bar 110 and away from the support column 400 is 90-145 degrees, and the data recorded by the data inclinometer 300 is 10-15 degrees. 00, a crowbar device is used to fix the reinforcement 600. At this time, the operator moves the crowbar 110 to change the data of the data inclinometer 300 to the specified data, and then the operator welds the reinforcement 600. In the present application, the data inclinometer 300 quantifies the prying angle of the crowbar 100 through the display of the angle. The operator can intuitively judge whether the prying angle meets the requirements through the data of the data inclinometer 300, so that the door panel 200 will not be damaged while the reinforcement 600 is fixed and welded, and the welding efficiency of the reinforcement 600 is improved.

[0046] In some embodiments, see Figure 1 The data inclinometer 300 is arranged at the supporting end 111. Specifically, the data inclinometer 300 is arranged on the side of the supporting column 400 and the prying head 120, so that the operator can intuitively see the data display of the data inclinometer 300 when fixing the reinforcing rib 600, avoiding the situation where the data inclinometer 300 is blocked by the operator's hand when it is arranged at the other end of the prying rod 110, making it difficult to observe.

[0047] In some embodiments, see Figure 1-Figure 2 The pry bar 110 has a connecting end surface 115, and the pry head 120 has a connecting surface 121, wherein the size of the connecting surface 121 matches the size of the connecting end surface 115, so that when the connecting surface 121 is connected to the connecting end surface 115, the connecting surface 121 coincides with the connecting end surface 115, thereby avoiding the existence of a sanitary dead corner at the connection between the connecting surface 121 and the connecting end surface 115.

[0048] In the embodiment of the present application, the pry bar 110 and the pry head 120 are detachably connected, wherein the pry bar 110 and the pry head 120 can be connected in a threaded manner, a snap connection, or the like. In the embodiment of the present application, the pry bar 110 and the pry head 120 are connected in a threaded manner. Specifically, a threaded rod 121a is provided at the center of the connecting surface 121, and a threaded hole 115a is provided at the center of the connecting end surface 115. The pry head 120 and the pry bar 110 are connected through the threaded rod 121a and the threaded hole 115a, so that the connection between the pry head 120 and the pry bar 110 is detachable, and thus when the pry head 120 or the pry bar 110 is damaged, it can be repaired or replaced by disassembling the pry head 120 or the pry bar 110, so that the maintenance of the crowbar device is simple. At the same time, when the crowbar device is not in use, the entire crowbar device can be stored according to the storage space or the pry head 120 and the pry bar 110 can be disassembled for storage, so that the storage method of the crowbar 100 is varied and applicable to a wide range of applications.

[0049] In some embodiments, see Figure 1 The support column 400 and the support end 111 can be connected by threaded connection, snap-on connection and other connection methods. In the embodiment of the present application, the support column 400 and the support end 111 are threadedly connected. Specifically, one end of the support column 400 is provided with an external thread, and the support end 111 is provided with a threaded hole 115a with an internal thread. Specifically, the support column 400 and the support end 111 are threadedly connected through the end of the support column 400 with the external thread and the threaded hole 115a of the support end 111. When the support column 400 or the support end 111 is damaged, the operator can repair or replace it by disassembling the support column 400 or the support end 111, which makes the maintenance of the crowbar device simple. At the same time, when the crowbar device is not in use, the entire crowbar device can be stored according to the storage space or stored by disassembling the support column 400 and the support end 111, so that the storage method of the crowbar 100 is varied and applicable to a wide range.

[0050] In some embodiments, see Figure 1 The support column 400 is provided with a support pad 410 that matches the shape and size of the support column 400, so that the support pad 410 can cover the support column 400, and the support pad 410 is arranged at the end of the support column 400 away from the pry bar 110, wherein the support pad 410 and the support column 400 are detachably connected. Specifically, a threaded rod 121a is provided at the center of one side of the support pad 410 facing the support column 400, and a threaded hole 115a is provided at the center of the end face of the support column 400 facing the support pad 410. The support pad 410 is threadedly connected to the support pad 410. When the support pad 410 is damaged, the support pad 410 can be replaced by disassembling the support pad 410, thereby reducing the maintenance cost.

[0051] Among them, the side of the support pad 410 facing away from the support column 400 can be spherical. When the reinforcement rib 600 is fixedly welded, the support pad 410 is against the working plane of the door panel 200 or the reinforcement rib 600. When the operator moves the pry bar 110, since the support pad 410 is in the shape of a spherical body, the support pad 410 will not cause resistance to the crowbar 100 during the prying process of the pry bar 110. At the same time, the spherical design makes it difficult for the support pad 410 to cause damage to the door panel 200 or the reinforcement rib 600 when they come into contact with them.

[0052] At the same time, the material of the support pad 410 can be made of rubber or other materials, so that the support pad 410 has strong toughness and surface friction, thereby making it difficult for the pry bar 110 to slide during the prying process, and reducing the probability of damage to the door panel 200 or the reinforcement rib 600 of the support pad 410.

[0053] In some embodiments, see Figure 1 The crowbar 100 also includes an anti-slip cover 500. The crowbar 110 is provided with a moving end 112. The moving end 112 and the supporting end 111 are arranged at two ends of the crowbar 110 opposite to each other. Specifically, the anti-slip cover 500 is sleeved on the moving end 112, wherein the anti-slip cover 500 is made of materials such as rubber. When an operator holds the moving end 112 to pry the crowbar device, since the anti-slip cover 500 is sleeved on the moving end 112, it is not easy for the operator's palm to slip and the crowbar 110, and the operator can hold the crowbar 110 with less force.

[0054] In some embodiments, see Figure 1-Figure 2 The crowbar 110 also has a plurality of sub-connecting rods 113, and the plurality of sub-connecting rods 113 are threadedly connected to each other in pairs, wherein the support end 111 and the movable end 112 are respectively arranged on two sub-connecting rods 113 located at the outermost ends of the plurality of sub-connecting rods 113, so that the crowbar device can be adjusted in length by disassembling the sub-connecting rods 113 according to the usage requirements of the door panel 200 or the operator, and the crowbar 110 can be repaired by disassembling the sub-connecting rods 113, thereby reducing the repair cost.

[0055] The working principle of the crowbar device provided in the embodiment of the present application is as follows:

[0056] In the embodiment of the present application, the data inclinometer 300 is arranged in the groove 114 of the pry bar 110, and the pry head 120 is bent relative to the pry bar 110 and is arranged at one end of the pry bar 110. When the reinforcement 600 of the door panel 200 is fixedly welded, for example, when the reinforcement 600 of the door panel 200 of the KYN28A-12 high-voltage switch cabinet is fixedly welded, a crowbar device is used to fix the reinforcement 600. At this time, when the bending angle of the pry head 120 relative to the rod body of the pry bar 110 is 90-180 degrees, the data recorded by the data inclinometer 300 is 10-15 degrees. When the reinforcement 600 of the door panel 200 of the KYN28A-12 high-voltage switch cabinet is fixedly welded, the crowbar device is used to fix the reinforcement 600. At this time, the operator moves the crowbar 110 to change the data of the data inclinometer 300 to the specified data, and then the operator welds the reinforcement 600.

[0057] In the present application, the data inclinometer 300 quantifies the prying angle of the crowbar 100 by displaying the angle. The operator can intuitively judge whether the prying angle meets the requirements through the data of the data inclinometer 300, thereby preventing damage to the door panel 200 while performing the fixed welding of the reinforcement rib 600 and improving the welding efficiency of the reinforcement rib 600.
