Description

Technical Field

[0001] The utility model belongs to the field of ultra-high voltage equipment, and in particular relates to a flexible connection structure between a load-bearing frame and a support seat of an ultra-high voltage equipment. Background Art

[0002] The support seat, bearing frame, high pressure processing chamber and sealing plug are the main structures of ultra-high pressure equipment. Among them, the bearing frame is a very important component, and its main function is to withstand the ultra-high pressure at both ends of the processing chamber and install other components.

[0003] The load-bearing frame is both a load-bearing component and a mounting base for other components. The load-bearing frame is a circular structure. As a mounting base, the load-bearing frame itself needs to have sufficient rigidity. When the load-bearing frame is subjected to ultra-high pressure, it will inevitably deform, causing the positions of other components installed on it to change. The load-bearing frame includes horizontal sections at the upper and lower positions and vertical sections at the left and right positions. According to the force analysis, the upper and lower sides of the hollow part of the load-bearing frame (that is, the horizontal section) are the main deformation areas. Deformation will cause the horizontal section of the load-bearing frame to be slightly elongated and the overall width of the load-bearing frame to be slightly thinner. At present, the load-bearing frame is usually directly and rigidly connected to the support seat. When the above deformation occurs, the support seat will also deform accordingly. Repeated deformation of the support seat will cause the positions of other components installed on it to change, such as the oil cylinder and position sensor used to push the high-pressure processing chamber base to move. When this change causes a large error, the position needs to be recalibrated, and the bolts or welding points at the connection between the support seat and the load-bearing frame will also break. Therefore, how to solve these problems has a great impact on the position accuracy of other components installed on the support seat and the service life of the connecting components. Utility Model Content

[0004] (1) Technical problems solved:

[0005] In view of the fact that in the prior art the load-bearing frame is usually directly and rigidly connected to the support seat, which may affect the position accuracy of other components and the service life of the connected components, the utility model designs a structure in which the load-bearing frame and the support seat are flexibly connected, so that the load-bearing frame can adaptively move within the groove of the support seat when deformed by force, thereby greatly reducing the stress on the support seat and preventing the support seat from deforming, thereby solving the problem of the influence of the pressure deformation of the load-bearing frame on other components.

[0006] (2) The technical solution adopted by the utility model is as follows:

[0007] A flexible connection structure between a load-bearing frame and a support seat of an ultra-high voltage equipment comprises a load-bearing frame and a support seat, a notch is provided on the support seat, the load-bearing frame is inserted in the notch, a wedge is provided in the middle of the bottom surface of the notch, bevels are symmetrically provided on both sides of the top of the wedge, an bevel guide groove is provided at the bottom of the load-bearing frame at a position corresponding to the wedge, two side walls of the bevel guide groove match the bevels on both sides of the wedge, the top of the wedge is located inside the bevel guide groove, and the side walls of the bevel guide groove contact the bevels at the corresponding position, waist-shaped holes are provided on both sides of the notch on the support seat, the length direction of the waist-shaped holes is consistent with the length direction of the load-bearing frame, a connecting hole is provided at a position corresponding to the waist-shaped hole on the load-bearing frame, and fixing pins are provided in the waist-shaped hole and the corresponding connecting hole.

[0008] A further technical solution is that a keyway is provided in the middle of the inner bottom surface of the notch, and the lower part of the wedge block is located in the keyway and is fixed to the support seat.

[0009] A further technical solution is that a wear-resistant pad is provided between the load-bearing frame and the inner bottom surface of the slot.

[0010] A further technical solution is that the connecting hole is a threaded hole, and the fixing pin is threadedly connected inside the connecting hole.

[0011] (3) Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] A notch is provided on the support seat, and the load-bearing frame is inserted into the notch. Since waist-shaped holes are provided on both sides of the notch on the support seat, the length direction of the waist-shaped holes is consistent with the length direction of the load-bearing frame. Connecting holes are provided on the load-bearing frame at positions corresponding to the waist-shaped holes. Fixed pins are provided in the waist-shaped holes and the corresponding connecting holes. When the load-bearing frame is deformed and its length is slightly elongated, the fixed pins will make adaptive relative movements in the waist-shaped holes accordingly. In this way, the support seat can support the load-bearing frame without being affected by the deformation of the load-bearing frame.

[0013] A wedge block is arranged in the middle of the bottom surface of the slot, and bevels are symmetrically arranged on both sides of the top of the wedge block. An bevel guide groove is arranged at the bottom of the load-bearing frame corresponding to the wedge block. The two side walls of the bevel guide groove match the bevels on both sides of the wedge block. The top of the wedge block is located inside the bevel guide groove, and the side walls of the bevel guide groove are in contact with the bevels at the corresponding position. In this way, when the overall width of the load-bearing frame becomes slightly thinner, the load-bearing frame can still be kept in the center position of the slot under the cooperation of the bevel guide groove and the wedge block, thereby ensuring the position accuracy between the load-bearing frame and the support seat under the flexible connection condition.

[0014] A flexible connection is adopted between the load-bearing frame and the support seat. The stress caused by the deformation of the load-bearing frame is transmitted to the support seat very little, so the support seat will not be deformed, which ensures the position accuracy of other components installed on it and extends the service life of the equipment. The wedge block between the load-bearing frame and the support seat has a guiding function, which can make the load-bearing frame automatically return to the center after unloading.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 6 A flexible connection structure between a load-bearing frame and a support seat of an ultra-high voltage equipment comprises a load-bearing frame 1 and a support seat 2, wherein a notch 3 is provided on the support seat 2, the load-bearing frame 1 is inserted into the notch 3, a wedge 4 is provided in the middle of the inner bottom surface of the notch 3, and bevels 5 are symmetrically provided on both sides of the top of the wedge 4, an angled guide groove 6 is provided at the bottom of the load-bearing frame 1 at a position corresponding to the wedge 4, and the two side walls of the angled guide groove 6 match the angles 5 on both sides of the wedge 4, the top of the wedge 4 is located inside the angled guide groove 6, and the side walls of the angled guide groove 6 are in contact with the angles 5 at the corresponding position, waist-shaped holes 7 are provided on both sides of the notch 3 on the support seat 2, and the length direction of the waist-shaped holes 7 is consistent with the length direction of the load-bearing frame 1, and a connecting hole 8 is provided on the load-bearing frame 1 at a position corresponding to the waist-shaped hole 7, and a fixing pin 9 is provided in the waist-shaped hole 7 and the corresponding connecting hole 8.

[0023] When in use, the connecting hole 8 is a threaded hole, and the fixing pin 9 is threadedly connected to the inside of the connecting hole 8. The fixing pin 9 can choose a bolt that matches the connecting hole 8. The bolt passes through the waist-shaped hole 7 and is screwed into the connecting hole 8, but the bolt is not completely tightened. When the load-bearing frame 1 is stretched under force, it can adaptively move in the "U"-shaped groove 3, and shrink and move toward the middle when the force is unloaded, thereby realizing a flexible connection between the support seat 2 and the load-bearing frame 1. The top bevel angle 5 of the wedge block 4 that plays a guiding role is 45°, and the lower end is a right angle. The upper end of the wedge block 4 cooperates with the bevel guide groove 6 at the bottom of the load-bearing frame 1. In this way, when the overall width of the load-bearing frame 1 becomes slightly thinner, the bevel guide groove 6 will also shrink slightly accordingly, so the load-bearing frame 1 will rise slightly, and the margin of the rise is within the matching range of the fixing pin 9 and the waist-shaped hole 7, that is, the width of the waist-shaped hole 7 is slightly larger than the fixing pin 9, so that there is also room for movement between the two in the width direction of the waist-shaped hole 7.

[0024] A key slot 10 is provided in the middle of the bottom surface of the slot 3 , and the lower part of the wedge block 4 is located in the key slot 10 and is fixed to the support seat 2 to realize the connection between the wedge block 4 and the support seat 2 , and the wedge block 4 and the support seat 2 are fixed by screws.

[0025] A wear-resistant pad 11 is arranged between the load-bearing frame 1 and the inner bottom surface of the slot 3. The wear-resistant pad 11 is made of hard copper alloy and has wear-resistant and self-lubricating effects. The wear-resistant pad 11 can prevent wear caused by direct friction between the load-bearing frame 1 and the inner bottom surface of the slot 3.

[0026] The above are only preferred embodiments of the present invention.
