Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for billet production and processing, specifically to an auxiliary billet lifting tool for buffering and shock absorption. Background Technology

[0002] In the production and processing of ceramic and brick blanks, the blanks are fragile and have low structural strength. During transportation and handling, they are prone to cracking and breakage due to external impacts, vibrations, or uneven clamping forces. This not only leads to waste of raw materials and increased production costs, but also affects production efficiency and product qualification rate. Therefore, the non-destructive handling and transportation of blanks is a key requirement in the production process of this field.

[0003] Currently, the industry has gradually replaced purely manual lifting and placing with semi-automatic or mechanized billet lifting equipment to complete the transfer operation. The structure and working principle of the mainstream equipment are as follows: This type of billet lifting tool includes a slide rail assembly, lifting arm, claw clamp, and control box. The slide rail assembly consists of a horizontal rail fixed to the factory ceiling and a longitudinal rail that can slide along the length of the horizontal rail. The horizontal and longitudinal rails intersect perpendicularly to form a two-dimensional moving track. A top plate that can move along the length of the longitudinal rail is suspended below it. The upper end of the lifting arm is connected to the lower surface of the top plate through a rotating shaft to realize the horizontal turning of the lifting arm. The lower end of the lifting arm is connected to a base plate that can be raised and lowered in the vertical direction (the lifting drive is mostly pneumatic or electric push rod). The claw clamp is fixed to the front side of the base plate and consists of two symmetrically arranged clamping rods. The clamping rods form a clamping opening for holding the billet. The control box is installed on the rear side of the base plate. There are handles on the left and right sides of the box. The internal drive motor and transmission mechanism are integrated. The operator triggers the motor by rotating the handle, which drives the two clamping rods to move closer or further apart in the horizontal direction, thereby realizing the clamping and releasing of the clamping opening. In actual operation, the operator moves the equipment along the slide rail assembly to above the flatcar, adjusts the height of the jaws by raising and lowering the base plate, clamps the billet, moves it above the conveyor belt bracket, and releases the jaws to complete the billet transfer. Compared to purely manual lifting and placing, this process reduces labor intensity and improves the stability of the transfer path through the directional movement of the slide rails.

[0004] However, the existing mechanized billet lifting equipment still has shortcomings in practical applications: 1. Poor buffering and shock absorption, leading to high risk of billet breakage due to stress concentration: Existing equipment often uses metal (such as Q235 steel) or hard plastic (such as ABS engineering plastic) for its gripper body, resulting in rigid contact with the billet. Although some equipment attaches a single layer of rubber (usually 1-2mm thick, mostly natural rubber) to the inside of the gripper bars, this rubber only increases the coefficient of friction for anti-slip purposes and cannot effectively absorb the impact energy during lifting and lowering or the vibration energy during movement. When the billet is rigidly clamped, the clamping force applied by the gripper bars easily creates stress concentration in localized areas of the billet (especially at the edges and corners). Combined with the combined effects of impact and vibration, this still results in a billet breakage rate of 1.5%-3%.

[0005] 2. Inconvenient maintenance and high long-term operating costs of the buffer structure: Existing equipment often uses an integrated design with adhesive bonding, forming an inseparable connection with the gripper body. Because the buffer structure continuously contacts and rubs against the blank, and the blank surface may retain small amounts of dust and moisture, the buffer material is prone to wear (surface smoothing) and aging (hardening and cracking) after a 3-6 month usage cycle, losing its original buffering performance. At this point, the buffer structure needs to be replaced. However, due to the integrated design, replacement requires complete disassembly of the gripper (removing fixing bolts and disconnecting the transmission mechanism). Maintenance time for a single gripper can be as long as 30-45 minutes, resulting in cumbersome maintenance operations, long downtime, and increased maintenance consumable costs.

[0006] In summary, current billet lifting tools suffer from poor buffering and shock absorption, high billet breakage rate, and inconvenient maintenance, failing to fully meet the industry's production needs for non-destructive, efficient, and stable billet lifting and transfer. Therefore, developing an auxiliary billet lifting tool with effective buffering and shock absorption, high clamping stability, and convenient maintenance has become an urgent problem to be solved in the field of billet production and processing auxiliary equipment technology. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary billet lifting tool for buffering and shock absorption, aiming to solve the problems of poor buffering and shock absorption effect, high billet breakage rate, and inconvenient maintenance of buffer structure in existing mechanized billet lifting equipment.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An auxiliary billet lifting tool for buffering and shock absorption includes a base plate and a jaw clamp. The jaw clamp is located on the front side of the base plate and includes two opposing clamping rods. A clamping opening for clamping the billet is formed between the two clamping rods. A plurality of buffer blocks are arranged along the length of the inner side of the clamping rods. The buffer blocks are used to buffer and absorb shock on the billet and increase the friction between the clamping rods and the billet when lifting and moving the billet. The buffer blocks are made of high-density polyurethane foam and are detachably connected to the clamping rods.

[0009] Compared with existing technologies, the buffer and shock-absorbing auxiliary billet lifting tool using the above-mentioned technical solution has the following beneficial effects: This invention, employing a buffer and shock-absorbing auxiliary billet lifting tool, differs from existing equipment where the jaws directly contact the billet in a rigid manner. High-density polyurethane foam possesses excellent elastic deformation capabilities. When the clamping rod holds the billet, the buffer block can deform to conform to the billet surface, evenly distributing the clamping force, originally concentrated at the edges and corners of the billet, to the contact surface between the buffer block and the billet, thus preventing billet cracking caused by localized stress concentration. The porous structure and high energy absorption characteristics of the high-density polyurethane foam can directly act on the "impact during lifting" and "vibration during transport." During lifting, the buffer block can cushion the instantaneous impact force between the jaws and the billet, preventing damage to the billet due to hard collisions; during transport, it can absorb vibration energy transmitted from the sliding rail movement and the workshop environment, preventing cumulative vibration damage to the internal structure of the billet. This invention's auxiliary billet lifting tool can reduce the billet breakage rate, is especially suitable for transporting large-sized billets, reduces raw material waste, ensures product qualification rate, and reduces rework and supplementary production costs caused by billet breakage.

[0010] Compared to the 1-2mm thick natural rubber sheets used in existing equipment, high-density polyurethane foam has a higher surface friction coefficient, and its elastic bonding properties increase the actual contact area with the blank. Even with a small amount of dust or moisture remaining on the blank surface, it can still stably hold the blank, preventing it from slipping during transport. High-density polyurethane foam also exhibits superior wear resistance and aging resistance compared to traditional natural rubber. Its resistance to dust abrasion reduces the rate of surface smoothing, and its resistance to moisture erosion slows down material hardening and cracking, extending the lifespan of the buffer block and reducing maintenance frequency and consumable replacement costs.

[0011] This invention completely solves the problem of cumbersome maintenance of existing buffer structures by designing a detachable connection between the buffer block and the clamping rod. The detachable design means that only the failed buffer block needs to be replaced during maintenance, without having to replace the main clamping body at the same time, greatly reducing the waste of consumables; at the same time, the simplified disassembly and assembly process reduces the technical proficiency requirements of the staff, reduces labor costs, and avoids production interruption losses caused by prolonged equipment downtime.

[0012] In a preferred solution, tool-free disassembly and assembly throughout the entire process is realized, which further improves maintenance efficiency. During installation, an operator only needs to align the buckle groove with the clamping rod and gently push the buffer block in the horizontal direction; the clamping rod will drive the clamping block to automatically retract into the upper wall of the buckle groove by pressing the inclined surface; after the clamping rod completely enters the buckle groove, the spring automatically resets to push the clamping block to extend out, completing locking, and the entire installation process does not require manually pressing the clamping block. During disassembly, the operator only needs to gently pull up the handle to directly drive the clamping block to retract into the upper wall of the buckle groove, the locking of the buckle groove on the clamping rod is released instantly, and the disassembly can be completed by pulling the buffer block in the reverse direction; the grip design of the handle conforms to ergonomics, allowing fingers to exert force naturally and avoiding hand fatigue caused by repeated pressing.

[0013] Preferably, a buckle in a "匚"-shape is integrally formed on the back of the buffer block, a buckle groove adapted to the shape of the clamping rod is formed inside the buckle, and a clamping block capable of expanding and contracting in the up-down direction is provided on the upper wall of the buckle groove; the outer end of the clamping block adopts a vertical surface on the side facing the inside of the buckle groove, the clamping rod is buckled in the buckle groove, and the vertical surface of the clamping block abuts against the outer side of the clamping rod, so as to prevent the clamping rod from detaching from the buckle groove.

[0014] Preferably, a spring is provided at the inner end of the clamping block, when the clamping block retracts into the upper wall of the buckle groove, the spring is compressed; when the clamping block extends out of the upper wall of the buckle groove, the spring resets; the outer end of the clamping block adopts an inclined surface on the side facing the outside of the buckle groove.

[0015] Preferably, a handle in a "ㄇ"-shape is provided above the buckle, and the handle is fixedly connected with the clamping block; when the handle is pulled up, the handle drives the clamping block to retract into the upper wall of the buckle groove, and the spring is compressed; when the handle is released, the spring resets and drives the clamping block to extend out of the upper wall of the buckle groove.

[0016] Preferably, a positioning block is provided on the inner side of the clamping rod, a positioning groove adapted to the shape of the positioning block is provided on the surface of the inner wall of the buckle groove that fits the inner side of the clamping rod, and the positioning block is clamped in the positioning groove to limit the movement of the buffer block along the length direction of the clamping rod. Even if the equipment is affected by the vibration of the slide rail during transportation, or the clamping rod produces slight deformation under the reaction force when clamping the blank, the clamping structure of the positioning block and the positioning groove can firmly fix the position of the buffer block and avoid cumulative displacement. When an operator installs the buffer block, only by aligning the positioning groove of the buckle groove with the positioning block of the clamping rod can the installation position of the buffer block be quickly determined without repeated adjustment, which avoids poor buffering caused by installation deviation.

[0017] Preferably, the height of the buffer block is not less than the height of the clamping rod, so as to ensure that the buffer block can completely cover the contact area between the clamping rod and the blank, completely eliminating the possibility that the rigid part of the clamping rod directly touches the blank.

[0018] Preferably, the clamp is equipped with a support rod for abutting against the arc groove at the rear of the billet. The support rod is a cylinder placed horizontally along the length of the clamp rod and is fixedly connected to the base plate. The outer circumference of the support rod is wrapped with a buffer sleeve for cushioning and shock absorption of the billet. The arc-shaped outer circumference of the support rod can perfectly fit the inner wall of the arc groove at the rear of the billet, adapting to arc grooves of different small curvatures (such as common billet arc grooves with radii of 5-20cm). This transforms the "suspended and unsupported" condition into "surface contact support," making the billet more evenly stressed: the supporting force of the support rod can directly offset part of the clamping force's pulling effect on the rear of the billet, avoiding the tensile stress caused by "side compression and no rear support" on the inner wall of the arc groove. At the same time, it transfers the stress concentration area from the inner wall of the arc groove to the "contact surface between the buffer sleeve and the billet," and further evenly disperses the stress through the elastic deformation of the buffer sleeve, reducing the breakage rate of the billet with the arc groove. The close fit between the support rod and the arc groove of the billet can accurately lock the position of the billet in the clamp, preventing the billet from swaying back and forth or shifting left and right due to vibration during transfer. This ensures that the billet is accurately aligned when transferred to the conveyor belt bracket, reducing the problem of "bill placement deviation and collision with bracket" caused by positioning deviation, and further improving transfer efficiency and pass rate.

[0019] Preferably, each clamping rod has a protrusion at its end that extends into the clamping opening. The outer wall of the protrusion, which contacts the billet, is made of silicone. The protrusions of the two clamping rods abut against the two front sides of the billet to prevent the billet from detaching from the clamping opening. Once the two front sides of the billet are blocked by the protrusions, the tendency for the billet to slide forward is directly cut off. Combined with the support rod's abutment against the rear of the billet, the two form a two-way locking mechanism of "front blocking and rear pushing," firmly fixing the billet in the preset area within the clamping opening. Even if the equipment stops suddenly, turns, or is subjected to strong vibration, the risk of the billet slipping can be completely eliminated. Attached Figure Description

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] like Figures 1 to 8 The auxiliary billet lifting tool with buffering and shock absorption shown includes a base plate 10 and a jaw clamp 2. The jaw clamp 2 is located on the front side of the base plate 10 and includes two opposing clamping rods 21. A clamping opening 20 for clamping the billet 7 is formed between the two clamping rods 21. Several buffer blocks 41 are arranged along the length of the inner side of the clamping rods 21. The buffer blocks 41 are used to buffer and absorb shock on the billet 7 when lifting and moving it, and to increase the friction between the clamping rods 21 and the billet 7. The buffer blocks 41 are made of high-density polyurethane foam and are detachably connected to the clamping rods 21. The high-density polyurethane foam has excellent elastic deformation capability. When the clamping rods 21 clamp the billet 7, the buffer blocks 41 can conform to the surface of the billet 7 through their own deformation, and evenly distribute the clamping force originally concentrated on the edges and corners of the billet 7 to the contact surface between the buffer blocks 41 and the billet 7, avoiding cracking of the billet 7 caused by local stress concentration. The porous structure and high energy absorption properties of high-density polyurethane foam can directly mitigate the impact of lifting and placing as well as the vibration during transport. During lifting, the buffer block 41 cushions the instantaneous impact force between the claw clamp 2 and the billet 7, preventing damage to the billet 7 due to hard collisions. During transport, it absorbs vibration energy transmitted from the sliding rail movement and the workshop environment, preventing cumulative vibration damage to the internal structure of the billet 7. This auxiliary billet lifting tool reduces the breakage rate of the billet 7, is particularly suitable for transporting large-sized billets 7, reduces raw material waste, ensures product qualification rate, and lowers the costs of rework and replacement due to billet 7 breakage.

[0031] Wherein, the high-density polyurethane sponge has a higher surface friction coefficient, and its elastic fitting property can increase the actual contact area with the blank 7. Even when a small amount of dust and moisture remains on the surface of the blank 7, it can still clamp the blank 7 stably, preventing the blank 7 from slipping during transfer; the wear resistance and aging resistance of high-density polyurethane sponge are superior to traditional natural rubber. Its anti-dust wear capability can reduce the speed of surface smoothing, and its moisture erosion resistance property can delay the hardening and cracking of the material, prolonging the service life of the buffer block 41 and reducing the maintenance frequency and consumable replacement cost.

[0032] Wherein, the utility model completely solves the problem of cumbersome maintenance of the existing buffer structure by designing the detachable connection between the buffer block 41 and the clamping rod 21. The detachable design enables that only the failed buffer block 41 needs to be replaced during maintenance, and it is not necessary to replace the main body of the gripper 2 synchronously, which greatly reduces consumable waste; meanwhile, the simplified disassembly and assembly process reduces the requirement for technical proficiency of staff, cuts down manual operation costs, and avoids production interruption losses caused by long-term shutdown of equipment.

[0033] With reference to Figures 6 to 8 , a "匚"-shaped buckle is integrally formed on the back surface of the buffer block 41, a buckling groove 40 adapted to the shape of the clamping rod 21 is formed inside the buckle 4, and a clamping block 42 capable of expanding and contracting in the up-down direction is provided on the upper wall of the buckling groove 40; the outer end of the clamping block 42 adopts a vertical surface on the surface facing the inside of the buckling groove 40, the clamping rod 21 is buckled into the buckling groove 40, and the vertical surface of the clamping block 42 abuts against the outer side of the clamping rod 21, so as to prevent the clamping rod 21 from detaching from the buckling groove 40. A spring 44 is provided at the inner end of the clamping block 42, when the clamping block 42 retracts into the upper wall of the buckling groove 40, the spring 44 is compressed; when the clamping block 42 extends out of the upper wall of the buckling groove 40, the spring 44 resets; the outer end of the clamping block 42 adopts an inclined surface on the surface facing the outside of the buckling groove 40. A "ㄇ"-shaped handle 43 is arranged on the top of the buckle 4, the handle 43 is fixedly connected with the clamping block 42; when the handle 43 is pulled up, the handle 43 drives the clamping block 42 to retract into the upper wall of the buckling groove 40, and the spring 44 is compressed; when the handle 43 is released, the spring 44 resets and drives the clamping block 42 to extend out of the upper wall of the buckling groove 40. Tool-free disassembly and assembly in the whole process is realized, which further improves maintenance efficiency. During installation, a worker only needs to align the buckling groove 40 of the buckle 4 with the clamping rod 21 and push the buffer block 41 gently in the horizontal direction, the clamping rod 21 will squeeze the inclined surface to drive the clamping block 42 to automatically retract into the upper wall of the buckling groove 40; after the clamping rod 21 completely enters the buckling groove 40, the spring 44 automatically resets to push the clamping block 42 to extend out to complete locking, and the whole installation process does not require manually pressing the clamping block 42. During disassembly, a worker only needs to gently pull the handle 43 upward to directly drive the clamping block 42 to retract into the upper wall of the buckling groove 40, the locking of the buckling groove 40 to the clamping rod 21 is released instantly, and the disassembly can be completed by pulling the buffer block 41 in the reverse direction; the grip design of the handle 43 conforms to ergonomics, allowing fingers to exert force naturally and avoiding hand fatigue caused by repeated pressing.

[0034] With reference to Figure 3 and Figure 5 and Figure 7 The clamping rod 21 has a positioning block 23 on its inner side. The inner wall of the latching groove 40 has a positioning groove 45 that matches the shape of the positioning block 23 on the surface that fits against the inner side of the clamping rod 21. The positioning block 23 is engaged in the positioning groove 45 to restrict the movement of the buffer block 41 along the length of the clamping rod 21. Even if the equipment is affected by the vibration of the slide rail during transportation, or if the clamping rod 21 is slightly deformed by the reaction force when clamping the blank 7, the engaging structure of the positioning block 23 and the positioning groove 45 can firmly fix the position of the buffer block 41 and avoid cumulative displacement. When the operator installs the buffer block 41, they only need to align the positioning groove 45 of the latching groove 40 with the positioning block 23 of the clamping rod 21 to quickly determine the installation position of the buffer block 41 without repeated adjustments, thus avoiding poor buffering due to installation misalignment.

[0035] The height of the buffer block 41 is not less than the height of the clamping rod 21 to ensure that the buffer block 41 can completely cover the contact area between the clamping rod 21 and the billet 7. This completely eliminates the possibility of the rigid part of the clamping rod 21 directly contacting the billet 7.

[0036] Reference Figures 1 to 3 The clamp 20 is equipped with a support rod 11 for abutting against the arc groove 70 at the rear of the billet 7. The support rod 11 is a cylinder placed horizontally along the length direction perpendicular to the clamp rod 21. The support rod 11 is fixedly connected to the base plate 10. The outer circumference of the support rod 11 is wrapped with a buffer sleeve 12 for cushioning and shock absorption of the billet 7. The arc-shaped outer circumference of the support rod 11 can perfectly fit the inner wall of the arc groove 70 at the rear of the billet 7, adapting to arc grooves 70 with different small curvatures. This transforms the "suspended and unsupported" condition into a "surface contact support", making the billet 7 more evenly stressed: the supporting force of the support rod 11 can directly offset part of the clamping force on the rear of the billet 7, avoiding the tensile stress generated by the "squeezing on both sides and no support at the rear" on the inner wall of the arc groove 70. At the same time, it transfers the stress concentration area from the inner wall of the arc groove 70 to the "contact surface between the buffer sleeve 12 and the billet 7". The elastic deformation of the buffer sleeve 12 further evenly disperses the stress, reducing the breakage rate of the billet 7 with the arc groove 70. The close fit between the support rod 11 and the arc groove 70 of the billet 7 can accurately lock the position of the billet 7 within the clamp 20, preventing the billet 7 from swaying back and forth or shifting left and right due to vibration during transfer. This ensures that the billet 7 can be accurately aligned when transferred to the bracket 60 of the conveyor belt 6, reducing the problem of "the billet 7 being placed off-center and colliding with the bracket 60" caused by positioning deviation, and further improving transfer efficiency and pass rate.

[0037] Each clamping rod 21 has a protrusion 22 at its end that protrudes into the clamping opening 20. The outer wall of the protrusion 22 that contacts the billet 7 is made of silicone. The protrusions 22 of the two clamping rods 21 abut against the two sides of the front of the billet 7 to prevent the billet 7 from detaching from the clamping opening 20. Once the two sides of the front of the billet 7 are blocked by the protrusions 22, the tendency of the billet 7 to slide forward will be directly cut off. Combined with the support rod 11 supporting the rear of the billet 7, the two form a two-way locking of "front blocking and rear pushing", which firmly fixes the billet 7 in the preset area within the clamping opening 20. Even if the equipment stops suddenly, turns, or is subjected to strong vibration, the risk of the billet 7 slipping can be completely eliminated.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
