Description

Technical Field

[0001] The present application relates to the technical field of acetylene cracking, and in particular to a support structure for a spherical body to perform universal movement. Background Art

[0002] The acetylene cracking furnace is the core key equipment for producing acetylene by partial oxidation of natural gas. The cracking reaction is a rapid reaction under normal pressure and high temperature. The main by-reaction product is char. The char adheres to the inner wall of the reaction chamber of the acetylene cracking furnace and needs to be cleaned regularly.

[0003] At present, during the operation of the carbon cleaning mechanism of the acetylene cracking furnace, the lower end of the carbon cleaning connecting rod needs to be provided with a fixed support for point positioning and universal rotation, as well as axial movement of the carbon cleaning connecting rod; the traditional fixed support structure is to rotate the universal ball on the inner wall of the furnace body through the fixing part, and then pass the carbon cleaning connecting rod through the universal ball, and the carbon cleaning connecting rod can slide in the universal ball along the axial direction, and the carbon cleaning connecting rod can be universally rotated on the fixing part through the universal ball, but the traditional movable support structure has the following main disadvantages:

[0004] 1. Some traditional fixing parts have complex structures, easy to get stuck in motion, and the ball cannot rotate flexibly or has limited direction.

[0005] 2. The universal ball structure makes it difficult to process and assemble the required fixings, and it is difficult to control the matching clearance, resulting in uncontrollable clearance and wrapping force between the universal ball and the fixings;

[0006] 3. The friction between the universal ball and the fixed support is large, the operation is not smooth, and the adjustability is poor, which makes maintenance and care troublesome.

[0007] Therefore, it is urgent to design a supporting structure that can overcome the above disadvantages, so that the sphere can be quickly rotated and installed in the furnace body, and the coaxiality of the sphere can be adjusted conveniently. Utility Model Content

[0008] In order to facilitate the rapid installation of the support structure and improve the ability of the support structure to adjust the coaxiality of the sphere, the present application provides a support structure in which the sphere can perform universal movement.

[0009] The present application provides a support structure for a spherical body to perform universal motion, which adopts the following technical solution:

[0010] A support structure for a ball to perform universal movement, comprising a support plate arranged on the inner wall of a furnace body, two groups of sliding seats slidably arranged on the support plate and providing rotational support for opposite ends of the ball, a truncated cone-shaped through hole being opened on the sliding seat, the through holes on the two groups of sliding seats jointly pressing against the ball and adjusting the coaxiality of the ball, a pushing and locking assembly arranged on the support plate and used to push the two groups of sliding seats to approach each other and press against the ball.

[0011] By adopting the above technical solution, the support plate is fixed on the furnace body, and the sphere is placed in the through hole between the two groups of sliding seats. Then, the two groups of sliding seats are pushed closer to each other by pushing the locking assembly and the inner side walls of the through hole are pressed against the sphere and the sphere is supported for rotation. The sliding seat is pushed and the coaxiality of the sphere is adjusted by pushing the locking assembly, so as to facilitate the rapid installation of the support structure and improve the ability of the support structure to adjust the coaxiality of the sphere.

[0012] Further, the push-locking assembly comprises:

[0013] A pressure plate, wherein two groups of the pressure plates are provided and are respectively located on both sides of the support plate, and the two groups of the pressure plates are respectively pressed against the two groups of sliding seats and push the two groups of sliding seats closer to each other;

[0014] The locking bolts pass through the two groups of pressing plates and the supporting plate and lock the two groups of pressing plates on the supporting plate through locking nuts.

[0015] By adopting the above technical solution, the position of the locking bolt on the locking bolt is adjusted, thereby adjusting the distance between the two sets of pressure plates and the support plate, and then adjusting the position of the ball in the sliding seat to ensure the coaxiality of the ball in the sliding seat.

[0016] Furthermore, the pressure plate is provided with an avoidance hole for avoiding the ball and improving the pressing effect on the sliding seat. The avoidance hole is a truncated cone-shaped hole structure, and the top of the sliding seat and one end away from the ball is provided with an inclined surface that cooperates with the avoidance hole.

[0017] By adopting the above technical solution, when the pressure plate slides toward the support plate, the avoidance hole and the inclined surface cooperate with each other to push the sliding seat to slide toward another group of sliding seats; at the same time, the truncated cone-shaped avoidance groove decomposes the force of the pressure plate on the sliding seat into forces in the horizontal and vertical directions, thereby pushing the sliding seat to slide while reducing the probability of deformation and damage of the sliding seat under the force of the sphere.

[0018] Furthermore, the through hole is opened on the sliding seat and coincides with the axis of the sliding seat. The two groups of sliding seats are symmetrically arranged on the support plate. The diameter of the through hole at the opposite end of the two groups of sliding seats is larger than the diameter of the through hole at the opposite end. The two groups of sliding seats are close to each other and the two ends of the sphere are rotated to press against the side wall of the through hole.

[0019] By adopting the above technical solution, the truncated cone-shaped through hole provides rotational support for the sphere, and the force exerted by the sliding seat on the sphere is adjusted by adjusting the different positions of the sphere on the inner wall of the through hole. At the same time, the through hole of the truncated cone structure can quickly position the sphere and adjust the coaxiality of the sphere.

[0020] Furthermore, the taper of the truncated cone-shaped through hole on the sliding seat is 66 degrees.

[0021] By adopting the above technical solution, the taper of the truncated cone-shaped through hole is preferably 66 degrees, so as to facilitate the two sets of sliding seats to rotatably support the ball.

[0022] Furthermore, the taper of the avoidance hole on the pressure plate is 45 degrees.

[0023] By adopting the above technical solution, the horizontal force exerted by the pressure plate on the sliding seat is equal to the vertical force exerted by the pressure plate, which can well ensure that the pressure plate pushes the sliding seat to slide while reducing the probability of deformation damage to the sliding seat.

[0024] Furthermore, an adjustment pad for adjusting the distance between the pressing plate and the supporting plate is provided between the pressing plate and the supporting plate, and the thickness of the adjustment pad can be adjusted according to demand.

[0025] By adopting the above technical solution, the pressure plate is stably pressed against the support plate through the adjustment pad, and the distance between the pressure plate and the support plate is adjusted by switching the adjustment pads of different thicknesses, thereby adjusting the pressing plate's pressing and supporting effect on the sliding seat.

[0026] Furthermore, the sliding seat is made of PPL elastic material, and the surface of the spherical structure is subjected to HCr treatment.

[0027] By adopting the above technical solution, the PPL elastic material makes the sliding seat have a certain deformability, thereby increasing the contact area between the sliding seat and the ball; the PPL elastic material also has an extremely low friction coefficient and wear resistance. At the same time, the HCr treatment of the ball reduces the friction coefficient of the ball surface, improves the wear resistance of the ball surface, and ultimately reduces the friction and wear of the ball when it rotates on the sliding seat.

[0028] Furthermore, dust covers are installed on the opposite ends of the two groups of sliding seats to prevent dust from entering between the sliding seats and the spheres.

[0029] By adopting the above technical solution, the dust cover is used to prevent dust from entering the gap between the sliding seat and the ball, thereby ensuring that the friction coefficient between the ball and the sliding seat is low.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] By fixing the support plate on the furnace body, the sphere is placed in the through hole between the two groups of sliding seats, and then the two groups of pressure plates are respectively pressed against the two groups of sliding seats, and the locking bolts and locking nuts cooperate with each other and drive the two groups of pressure plates to approach each other, so as to push the two groups of sliding seats to approach each other and press against the sphere through the inner side walls of the through holes and support the sphere for rotation, and by adjusting the distance between the pressure plate and the support plate, the sliding seat is pushed to slide and the coaxiality of the sphere is adjusted, so as to facilitate the rapid installation of the support structure and improve the support structure's ability to adjust the coaxiality of the sphere.
