Specific embodiments
[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] The core of the present invention is to provide a drill floor large square tile hoisting tool. The design of the T-shaped lifting hook enhances the stability and reliability of the hoisting connection, and improves the hoisting safety of the drill floor large square tile.
[0033] The drill floor large square tile hoisting tool provided by the present invention includes at least two symmetrically arranged hoisting tool units. Each hoisting tool unit includes a hoisting tool main body 1 provided with a hoisting hole 11. A sliding shaft 2 is provided at the lower end of the hoisting tool main body 1, and a T-shaped lifting hook 7 is provided at the lower end of the sliding shaft 2. The length of the horizontal baffle at the bottom of the T-shaped lifting hook 7 is greater than the width of the rectangular lifting hole 011 of the drill floor large square tile 01;
[0034] A locking member and a limiting member for restricting the rotation of the T-shaped hook 7 in the rectangular lifting hole 011 are slidably sleeved on the sliding shaft 2 from top to bottom in sequence. When the locking member is locked in cooperation with the sliding shaft 2, the locking member can restrict the movement of the limiting member.
[0035] In the lifting tool unit, the lifting tool main body 1 is used to connect the lifting tool unit and the lifting equipment through the lifting hole 11. The material, structure and size of the lifting tool main body 1, as well as the shape and size of the lifting hole 11, can be determined with reference to existing lifting tools according to the actual production needs;
[0036] A T-shaped hook 7 is provided at the bottom of the lifting tool main body 1. The T-shaped hook 7 is used to be inserted into the rectangular lifting hole 011 of the rotary table square bushing 01 to realize the lifting connection between the lifting tool unit and the rotary table square bushing 01.
[0037] To prevent the T-shaped hook 7 from rotating to be parallel to the rectangular lifting hole 011 during the lifting process, resulting in the T-shaped hook 7 falling out, a limiting member for restricting the rotation of the T-shaped hook 7 in the rectangular lifting hole 011 is provided in the lifting tool unit. The limiting member can specifically be set as a limiting block, a limiting plate, etc.; <>
[0038] The limiting member can be set at a certain distance from the T-shaped hook 7 to limit the rotation range of the T-shaped hook 7 and avoid the T-shaped hook 7 rotating to be parallel to the rectangular lifting hole 011. Preferably, the limiting member is set to abut against the T-shaped hook 7. At this time, the limiting member can limit the rotation range of the T-shaped hook 7 to 0°.
[0039] Preferably, an anti-slip structure such as an anti-slip thread or an anti-slip cushion layer is provided on the side of the limiting member relatively close to the T-shaped hook 7. The anti-slip structure is used to increase the friction force between the limiting member and the T-shaped hook 7, thereby improving the limiting effect of the limiting member on the T-shaped hook 7.
[0040] To prevent the limiting member from jumping and falling out of the rectangular lifting hole 011 during the lifting process, a locking member for cooperating with the sliding shaft 2 to lock the limiting member is provided in the lifting tool unit. The locking member can be connected to the sliding shaft 2 by means of snap connection, threaded connection, etc. to prevent the movement of the limiting member during the lifting process.
[0041] The locking member can be set as a threaded sleeve spirally sleeved on the sliding shaft 2. By tightening the threaded sleeve downward, the threaded sleeve abuts against the limiting member to lock the limiting member;
[0042] The locking member can be set as a retaining ring 3 sleeved outside the sliding shaft 2 and a retaining pin 4 provided on the sliding shaft 2. The retaining pin 4 is slidably arranged in the retaining groove 31 of the retaining ring 3. By changing the cooperation state between the retaining pin 4 and the retaining groove 31, the height of the retaining ring 3 relative to the sliding shaft 2 is changed, thereby realizing the locking and loosening of the locking member;
[0043] The locking member can also be set as a locking pin, a fastening screw, etc. After passing through the locking member mounting hole of the limiting member, the locking member is connected and fixed to the sliding shaft 2.
[0044] The number of required sling units and the positions of the sling connection points of each sling unit are determined according to the number and distribution of the rectangular lifting holes 011 of the rotary table square bushing 01 in actual production.
[0045] For example, when there are two symmetrically arranged rectangular lifting holes 011 on the upper end surface of the rotary table square bushing 01, two symmetrically arranged lifting units can be used to sling and connect the two rectangular lifting holes 011 respectively, as Figure 7 and Figure 8 shown.
[0046] During use, first connect the lifting hole 11 of the sling unit to the lifting equipment through a shackle, and make at least two sling units located directly above the rotary table square bushing 01 to be lifted; then insert the T-shaped hook 7 of the sling unit into the rectangular lifting hole 011 of the rotary table square bushing 01, and rotate the T-shaped hook 7 so that the horizontal baffle of the T-shaped hook 7 is not parallel to the rectangular lifting hole 011. Preferably, rotate the T-shaped hook 7 by 90° so that the horizontal baffle is perpendicular to the rectangular lifting hole 011; then insert the limiting member into the rectangular lifting hole 011, use the limiting member to restrict the rotation of the T-shaped hook 7, and finally cooperate and lock the locking member with the sliding shaft 2 to restrict the movement of the limiting member.
[0047] When unlocking is required, first open the connection between the locking member and the sliding shaft 2, then take out the limiting member from the rectangular lifting hole 011, and finally rotate the T-shaped hook 7 and take out the T-shaped hook 7 from the rectangular lifting hole 011 to complete the unlocking.
[0048] In this embodiment, the T-shaped hook 7 is inserted into the rectangular lifting hole 011 of the rotary table square bushing 01, and the rotation of the T-shaped hook 7 relative to the rectangular lifting hole 011 is restricted by the limiting member, and the limiting member is locked by the locking member, effectively preventing the T-shaped hook 7 from coming out of the rectangular lifting hole 011, and making the horizontal baffle of the T-shaped hook 7 keep in contact with the bottom surface of the rectangular groove of the rectangular lifting hole 011, increasing the contact area between the hook and the rectangular lifting hole 011, improving the stability and reliability of the sling connection, and realizing the safe lifting of the rotary table square bushing 01.
[0049] In order to facilitate the transfer of the sling main body 1, a lifting handle 12 can be provided on the side of the sling main body 1. The lifting handle 12 can be used as the holding part of the sling main body 1. Preferably, the lifting handle 12 and the sling main body 1 are of an integral structure;
[0050] The specific structure, shape and size of the lifting handle 12 can be determined with reference to the holding positions such as the handles in existing mechanical equipment according to the needs in actual production, and will not be elaborated here.
[0051] Based on the above embodiments, the structure of the limiting member is defined. The limiting member includes a locking ring 5 for abutting against the upper end surface of the large square tile 01 of the drill disc and a locking pin 6 provided on at least one side of the locking ring 5. The locking pin 6 is used to insert into the rectangular lifting hole 011. Please refer to Figure 7 and Figure 8 .
[0052] Among them, the locking pin 6 is used to insert into the rectangular lifting hole 011. The width of the locking pin 6 is slightly smaller than the width of the rectangular groove of the rectangular lifting hole 011, so as to limit the rotation of the T-shaped lifting hook 7 in the rectangular lifting hole 011, thereby avoiding the unlocking of the T-shaped lifting hook 7 and the rectangular lifting hole 011.
[0053] In order to improve the limiting effect of the locking pin 6 on the T-shaped lifting hook 7, it is preferably set that the inner side surface of the locking pin 6 abuts against the outer side surface of the T-shaped lifting hook 7. By increasing the contact area between the locking pin 6 and the T-shaped lifting hook 7 and increasing the friction force between the two, the limiting effect is further improved.
[0054] The locking pin 6 needs to be inserted into the rectangular lifting hole 011, so the length H of the locking pin 6 needs to be greater than the thickness t of the rectangular groove of the rectangular lifting hole 011. It is preferably set that the length H of the locking pin 6 is equal to or greater than the sum of the thickness t of the rectangular groove of the rectangular lifting hole 011 and the height h of the horizontal baffle at the bottom of the T-shaped lifting hook 7, so as to improve the limiting effect of the locking pin 6 on the T-shaped lifting hook 7.
[0055] The locking pin 6 is provided on at least one side of the locking ring 5. The locking ring 5 is slidably sleeved on the sliding shaft 2. The locking ring 5 is used to mount the locking pin 6 on the sliding shaft 2; the specific shape and structure of the locking ring 5 are not limited as long as the locking ring 5 can slide relative to the sliding shaft 2.
[0056] In order to facilitate the processing and manufacture of the locking ring 5, it is preferably set that the locking ring 5 is a circular locking ring; in order to increase the friction force between the lifting unit and the large square tile of the drill tool 01 and limit the rotation of the T-shaped lifting hook 7 relative to the rectangular lifting hole 011, it is preferably set that the lower end surface of the locking ring 5 is a wedge-shaped surface, and the angle between the wedge-shaped surface and the vertical plane is the same as the lifting angle of the T-shaped lifting hook 7 relative to the horizontal plane during hoisting. Usually, the above-mentioned lifting angle is set to 75°-80°.
[0057] Based on the above embodiments, in order to limit the structure of the locking member, the locking member includes a retaining ring 3 and a stop pin 4. The stop pin 4 protrudes from the outer peripheral part of the sliding shaft 2 and is slidably sleeved in the retaining groove 31 of the retaining ring 3;
[0058] When the stop pin 4 is located at the high point of the retaining groove 31, the lower end surface of the retaining ring is in contact with the limiting member to limit the movement of the limiting member;
[0059] When the stop pin 4 is located at the low point of the retaining groove 31, the lower end surface of the retaining ring 3 is not in contact with the limiting member.
[0060] Among them, the stop pin 4 protrudes from the outer peripheral part of the sliding shaft 2. The stop pin 4 can be installed in the stop pin hole of the sliding shaft 2 by interference fit, or can be connected to the sliding shaft 2 by a threaded connection method, or can be connected to the sliding shaft 2 by a welding method.
[0061] In addition, the stop pin 4 and the sliding shaft 2 can be set as an integral structure.
[0062] In order to ensure the stable installation of the stop pin 4, preferably, one end of the stop pin 4 can be sleeved in the stop pin hole of the sliding shaft 2, and the stop pin 4 is welded to the sliding shaft 2. At the same time, the stop pin 4 and the sliding shaft 2 are connected by a thread pair and welding, effectively ensuring the installation strength of the stop pin 4 and guaranteeing the installation stability and reliability of the stop pin 4.
[0063] The retaining ring 3 is slidably sleeved outside the sliding shaft 2. A through retaining groove 31 is provided on the retaining ring 3. The retaining groove 31 usually has a component extending in the circumferential direction to prevent the stop pin 4 from sliding to the low point of the retaining groove 31 under its own weight, so that the stop pin 4 is unlocked during the hoisting connection process.
[0064] The retaining groove 31 can be set as an inclined groove, or can be set as a C-shaped groove or an L-shaped groove. The specific structures, dimensions and distributions of the retaining groove 31 and the stop pin 4 are determined according to the actual production needs and will not be elaborated here.
[0065] In this embodiment, the stop pin 4 of the sliding shaft 2 slides in the retaining groove 31 of the retaining ring 3. By changing the position of the stop pin 4 relative to the retaining groove 31, the height of the retaining ring 3 relative to the sliding shaft 2 can be changed, thereby realizing the sliding limit of the limiting member. The structure is simple, the operation is convenient, and the limiting effect on the limiting member is excellent.
[0066] Preferably, in order to improve the locking effect of the locking member, the stop pin 4 can be provided to penetrate the sliding shaft 2, and the retaining groove 31 is centrosymmetric about the axis of the retaining ring 3.
[0067] By setting the cooperation of two groups of stop pins 4 and retaining grooves 31, compared with the cooperation of a single group of stop pins 4 and retaining grooves 31, the contact area between the stop pin 4 and the retaining groove 31 is larger and the locking effect is stronger.
[0068] Of course, according to the size of the sliding shaft 2, more stop pins 4 and retaining grooves 31 can be set as appropriate. When the numbers of both the stop pin 4 and the retaining groove 31 are greater than or equal to 2, it is preferably set that the stop pins 4 are evenly arranged along the circumferential direction of the sliding shaft 2, and the retaining grooves 31 are evenly arranged along the circumferential direction of the retaining ring 3.
[0069] On the basis of the above embodiments, the structure of the anti-backlash groove 31 can be limited. It can be set that the anti-backlash groove 31 includes at least one short groove 311 and at least one L-shaped groove 312. The vertical groove of the L-shaped groove 312 is arranged along the axial direction of the anti-backlash ring 31, and the bottom of the vertical groove communicates with the short groove 311.
[0070] One end of the L-shaped groove 312 is a horizontal groove, and the other end is a vertical groove arranged along the axial direction of the anti-backlash ring 3; the vertical groove can be connected to the short groove 311 through another horizontal groove, or it can be set that the bottom of the vertical groove and the bottom of the short groove 311 are both communicated with the lower end surface of the anti-backlash ring 3, as Figure 5 shown.
[0071] The specific dimensions of the L-shaped groove 312 and the short groove 311 are determined according to the actual production needs. For the convenience of processing, it is preferably set that the end of the L-shaped groove 312 is located directly above the short groove 311.
[0072] In this embodiment, compared with the inclined groove, the horizontal groove of the L-shaped groove 312 can better prevent the locking pin 4 from sliding relative to the L-shaped groove 312 under the action of its own weight, and the locking effect is better.
[0073] Each embodiment in this specification is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same and similar parts among the embodiments can be referred to each other.
[0074] The above has introduced in detail the hoisting tool for the large square tile of the drill disc provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
