Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching technology, in particular to an APS alignment clamping device. Background Art

[0002] The APS (Automatic Positioning and Clamping System) is a key device in the CDQ process, ensuring accurate alignment and safe operation of the coke drum beneath the hoisting derrick. The system's core function is to achieve forced positioning of the drum through hydraulics, thereby improving operational precision and safety.

[0003] Based on the APS alignment clamping device disclosed in Chinese Patent Publication No. CN221192072U, the present invention relates to an APS alignment clamping device comprising a base, two left and right APS hydraulic cylinders, and clamping arms. The central portions of the clamping arms are movably hinged to the piston rods of the APS hydraulic cylinders. Slider slots are symmetrically arranged within the base, housing sliders. The bottom ends of the clamping arms are hinged to the outer ends of the sliders. Elastic members are positioned between the sliders and the base's slideway partitions. The APS hydraulic cylinders are connected to the rotary housing of the central rotary joint via oil pipes 1 and 2, respectively. The rotary shaft of the central rotary joint is connected to the oil tank via a hydraulic oil rigid pipe, and the rotary shaft of the central rotary joint is fixedly connected to the base. The present invention incorporates an elastic buffering device. When the rollers at the top of the clamping arms make hard contact with the coke drum trolley, the elastic member deforms to absorb the impact force. This linearly reduces the impact force on the coke drum trolley, protecting the transmission equipment and increasing the service life of the equipment components. This device solves the problem of hydraulic cylinder connection hoses being easily damaged by repeated bending.

[0004] According to the above patent, a sliding slider is provided on the base to deform the elastic part in the slider to absorb the impact force through the movement of the slider, so that the impact force of the coke tank trolley is reduced. The spring will store energy during the deformation buffering, so that when the spring is released, it will push the slider to reset, so that the tightening arm will push the coke tank trolley during the process of resetting the slider, affecting the positioning of the coke tank trolley, and thus affecting the loading of the coke tank trolley. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an APS alignment clamping device to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] An APS alignment clamping device includes a base, a slider slidably connected to the top of the base, an APS hydraulic cylinder hingedly connected to both sides of the slider on the top of the base, a clamping arm hingedly connected to the output end of the APS, the bottom end of the clamping arm being rotatably connected to the side wall of the slider, and a buffer assembly being provided on the side of the clamping arm facing away from the slider;

[0008] The buffer assembly includes a hydraulic rod and a transfer device. There are two hydraulic rods, which are symmetrically arranged on both sides of the APS hydraulic cylinder. The two ends of the hydraulic rod are respectively hinged to the output end of the APS hydraulic cylinder and the outer wall of the clamping arm. The transfer device is installed on the side wall of the output end of the APS hydraulic cylinder. The upper and lower sides of the transfer device are respectively connected to the two hydraulic rods through hydraulic pipes.

[0009] Furthermore, the transfer device includes a shell, a transfer cavity is defined in the shell, and connection ports communicating with the transfer cavity are connected to the upper and lower sides of the shell.

[0010] Furthermore, the diameter of the middle portion of the transfer cavity is reduced so that a constricted portion is formed in the transfer cavity.

[0011] Furthermore, a fire-resistant layer is wrapped around the surface of the hydraulic pipe.

[0012] Furthermore, a slide rail is fixedly connected to the top of the machine base along the length direction, and a slide groove connected to the slide rail is provided at the bottom of the slider.

[0013] Furthermore, the middle portion of the side of the clamping arm away from the APS hydraulic cylinder is gradually concave from the inside to the outside to form an arc-shaped installation groove, and a support block is rotatably connected in the installation groove.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. This APS alignment clamping device uses a buffer assembly to buffer the rotation of the clamping arm due to the pressure of the coke tank trolley by utilizing the damping force generated by the flow of liquid in the hydraulic rod. This ensures the buffering effect while preventing the rebound phenomenon caused by the disappearance of the pressure applied to the clamping arm, thereby ensuring the positioning effect of the APS alignment clamping device on the coke tank trolley.

[0016] 2. This APS alignment clamping device, by setting a support block, can use the larger contact surface of the support block to share the pressure of the coke tank trolley, thereby further reducing the pressure on the clamping arm and further improving the service life of the clamping arm. The arc-shaped mounting groove allows the support block to rotate in the mounting groove when under pressure, so that the support plane of the support block can always maintain the maximum contact surface with the coke tank trolley, which can effectively ensure the practicality of the support block.

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 4 The utility model discloses an APS alignment clamping device, which includes a base 1, a slider 2 being slidably connected to the top of the base 1, an APS hydraulic cylinder 3 being hinged on both sides of the slider 2 at the top of the base, a clamping arm 4 being hinged on the output end of the APS, the bottom end of the clamping arm 4 being rotatably connected to the side wall of the slider 2, and a buffer assembly 5 being provided on the side of the clamping arm away from the slider 2;

[0026] The buffer assembly 5 includes a hydraulic rod 51 and a transfer device 52. There are two hydraulic rods 51, which are symmetrically arranged on both sides of the APS hydraulic cylinder 3. The two ends of the hydraulic rod 51 are respectively hinged to the output end of the APS hydraulic cylinder 3 and the outer wall of the clamping arm 4. The transfer device 52 is installed on the side wall of the output end of the APS hydraulic cylinder 3. The upper and lower sides of the transfer device 52 are respectively connected to the two hydraulic rods 51 through hydraulic pipes 53.

[0027] In this embodiment, the observation Figure 1 It can be found that a slider 2 is slidably connected to the top of the machine base 1, and the top of the machine base 1 is hinged with APS hydraulic cylinders 3 on both sides of the slider 2. Then a clamping arm 4 is connected to the output end of the APS hydraulic cylinder 3, so that the bottom of the clamping arm 4 is hinged to the side wall of the slider 2. When the coke tank trolley moves to the clamping device area, the part where the clamping arm 4 extends out of the slider 2 can be used to buffer the positioning block at the bottom of the coke tank trolley, and at the same time, the movement of the coke tank trolley can be limited to achieve the positioning of the coke tank trolley.

[0028] However, since the coke tank trolley is very heavy, the clamping arm 4 will be damaged by the large pressure during buffering, thereby greatly shortening the service life of the clamping arm 4. Therefore, the clamping arm 4 is hinged to the output end of the APS hydraulic cylinder 3 so that when the clamping arm 4 contacts the coke tank trolley, the clamping arm 4 can be protected by rotating to unload the force.

[0029] However, due to the structural setting of the rotational unloading force, the connection strength between the clamping arm 4 and the output end of the APS hydraulic cylinder 3 will be reduced, which will also affect the service life of the clamping arm 4, resulting in an incomplete improvement in the service life of the clamping arm 4. Figure 1 and Figure 2 It can be found that by arranging two hydraulic rods 51 on the side of the clamping arm 4 away from the slider 2, the two hydraulic rods 51 are symmetrically arranged with the output end of the APS hydraulic cylinder 3 as the center, and then the two ends of the two hydraulic rods 51 are hinged to the output end of the APS hydraulic cylinder 3 and the outer wall of the clamping arm 4 respectively. When the clamping arm 4 is compressed and rotated, the two hydraulic rods 51 provide a buffer for the clamping arm 4, thereby reducing the pressure on the clamping arm 4.

[0030] And in Figure 2 It can also be found that a transferor 52 is fixedly connected to the side wall of the output end of the APS hydraulic cylinder 3, and the upper and lower sides of the transferor 52 are respectively connected to the two hydraulic rods 51 through hydraulic pipes 53, so that when the clamping arm 4 is compressed and rotated, by squeezing one of the hydraulic rods 51, the liquid in the hydraulic rod 51 passes through the hydraulic pipe 53 and the transferor 52 and enters the other stretched hydraulic rod 51, so that when the clamping arm 4 rotates, the damping force generated by the flow of liquid in the hydraulic rod 51 is used for buffering, which avoids the rebound phenomenon after the pressure applied to the clamping arm 4 disappears while ensuring the buffering effect, thereby ensuring the positioning effect of the APS alignment clamping device on the focus tank trolley.

[0031] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, the transfer device 52 includes a shell 521, a transfer chamber 6 is opened in the shell 521, and the upper and lower sides of the shell 521 are connected to the connection port 522 communicating with the transfer chamber 6;

[0032] The diameter of the middle portion of the transfer cavity 6 is reduced, so that a constricted portion 7 is formed in the transfer cavity 6 .

[0033] In this embodiment, when the hydraulic rod 51 is compressed or stretched, the hydraulic space within it changes, necessitating the extrusion or suction of hydraulic oil. When the clamping arm 4 is squeezed and rotated, one of the hydraulic rods 51 on either side of the clamping arm 4 is inevitably compressed while the other is stretched. Therefore, a transfer chamber 6 is provided in the middle of the housing 521. Connecting ports 522, which communicate with the transfer chamber 6, are connected to the upper and lower sides of the housing 521. These ports 522 are then connected to the hydraulic rods 51 via hydraulic pipes 53, allowing the hydraulic oil in the two hydraulic rods 51 to circulate. This eliminates the need for an additional fluid supply mechanism when the two hydraulic rods 51 are in use, effectively reducing the cost of the APS alignment clamping device.

[0034] And in Figure 3 It can be found that the middle diameter of the transfer chamber 6 is reduced, so that a constricted portion 7 is formed in the transfer chamber 6, which can be used to reduce the cross-section of the hydraulic oil flow, thereby increasing the damping force of the hydraulic oil flow, so that when the clamping arm 4 is pressurized, the hydraulic rod 51 can provide a stronger buffering effect to the clamping arm 4.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, the surface of the hydraulic pipe 53 is wrapped with a fire-resistant layer.

[0036] In this embodiment, when the coke blocks are loaded into the coke tank trolley, a small amount of coke blocks will inevitably leak, causing the high-temperature coke blocks to come into contact with the hydraulic pipe 53. Therefore, a refractory layer is wrapped around the surface of the hydraulic pipe 53 to avoid direct contact between the high-temperature coke blocks and the hydraulic pipe 53 and damage to the hydraulic pipe 53, thereby effectively ensuring the stability of the APS positioning clamping device.

[0037] The refractory layer is a high-temperature resistant structural material made from natural minerals such as bauxite, silica, magnesite, and dolomite.

[0038] In a further preferred embodiment of the present invention, Figure 1 As shown, a slide rail 8 is fixedly connected to the top of the machine base 1 along the length direction, and a slide groove 9 connected to the slide rail 8 is provided at the bottom of the slider 2.

[0039] In this embodiment, since the slider 2 will inevitably slide during the process of the clamping arm 4 rotating to unload the force, in order to ensure the sliding stability of the slider 2, a slide rail 8 is fixedly connected to the top of the machine base 1 along the length direction, and a slide groove 9 connected to the slide rail 8 is provided at the bottom of the slider 2. The slide rail 8 can be used to assist the sliding of the slider 2 to ensure the sliding stability of the slider 2, thereby improving the positioning accuracy of the coke tank trolley.

[0040] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the middle portion of the side of the clamping arm 4 away from the APS hydraulic cylinder 3 is gradually concave from the inside to the outside to form an arc-shaped installation groove 10, and a support block 11 is rotatably connected in the installation groove 10.

[0041] In this embodiment, the middle part of the side of the clamping arm 4 away from the APS hydraulic cylinder 3 is gradually concave from the inside to the outside to form an arc-shaped installation groove 10. A support block 11 is rotatably connected in the installation groove 10. The larger contact surface of the support block 11 can be used to share the pressure of the coke tank trolley, thereby further reducing the pressure on the clamping arm 4 and further improving the service life of the clamping arm 4.

[0042] After the clamping arm 4 is rotated under pressure, the state of the clamping arm 4 will be as follows: Figure 4 The change shown in the figure causes the angle of the support block 11 connected to the clamping arm 4 to change, thereby affecting the contact area between the support block 11 and the coke tank trolley, resulting in a weakening of the pressure dispersing effect of the support block 11. Therefore, the arc-shaped mounting groove 10 is provided to allow the support block 11 to rotate within the mounting groove 10 when under pressure, so that the support plane of the support block 11 always maintains the maximum contact area with the coke tank trolley, which effectively ensures the practicality of the support block 11.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
