[Solution] The steel sleeve device for receiving rectangular top pipes includes a base and a top pipe structure. This device installs a fixed hydraulic cylinder and a locking plate. By extending the fixed hydraulic cylinder, the locking plate is fixed to the inner surface and left side of the steel sleeve, securing the steel sleeve during top pipe operation. The L-shaped locking plate prevents the locking plate from being pinched between the steel sleeve and affecting the operation during top pipe operation. The rubber gasket prevents the steel sleeve from slipping, absorbs vibrations within the system, and prevents damage to equipment. This device also installs a limit plate, a bell-shaped opening, and a side plate. When the steel sleeve is lowered, the bell-shaped opening guides the steel sleeve, allowing it to pass between the limit plates and reach the specified position.

[0020] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, but not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments that can be obtained by a person skilled in the art without creative work are included in the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4. One embodiment of the present invention: a steel sleeve device for receiving rectangular top pipes includes a base seat 1 and a top pipe structure 3. A top pipe machine 2 is installed on the top of the base seat 1, a top pipe structure 3 is installed on the right side of the top pipe machine 2, a top pipe hydraulic cylinder 301 is installed on the right side of the top pipe machine 2, a mounting seat 302 is installed on the right side of the top pipe hydraulic cylinder 301, a fixed hydraulic cylinder 303 is installed outside the mounting seat 302, and limit plates 306 are installed on both sides of the base seat 1.

[0022] Specifically, the top tube hydraulic cylinder 301 is fitted and connected to the base seat 1, and two sets of top tube hydraulic cylinders 301 are installed. The mounting seat 302 forms a movable structure with the base seat 1 via the top tube hydraulic cylinder 301, and the extension of the top tube hydraulic cylinder 301 pushes the steel sleeve into the tunnel.

[0023] Specifically, the fixed hydraulic cylinder 303 is fixedly connected to the mounting seat 302, and multiple sets of fixed hydraulic cylinders 303 are installed. A locking plate 304 is connected to one end of the fixed hydraulic cylinder 303. The locking plate 304 is L-shaped, and the locking plate 304 forms a movable structure with the mounting seat 302 via the fixed cylinder 303. When the fixed hydraulic cylinder 303 is extended, the locking plate 304 is fixed to the inner surface and left side of the steel sleeve, fixing the steel sleeve during the cresting operation. The L-shaped locking plate 304 prevents the locking plate 304 from being caught between the steel sleeve and the cresting operation, which could affect the operation.

[0024] Specifically, packing 305 is glued to the outside of lock plate 304. Packing 305 is made of rubber and matches the dimensions of lock plate 304. Packing 305 prevents the steel sleeve from slipping, absorbs vibrations within the system, and prevents damage to equipment.

[0025] Specifically, two sets of limit plates 306 are installed, and the limit plates 306 are made of alloy steel. A bell-shaped opening 307 is installed at the top of the limit plate 306, and a side plate 308 is installed on the left side of the bell-shaped opening 307. When the steel sleeve is lowered, the bell-shaped opening 307 guides the steel sleeve, passing between the limit plates 306 to reach the specified position. This eliminates the need for manual alignment during the lifting operation, preventing injury to workers and improving safety. The side plate 308 prevents the steel sleeve from tilting to the left.

[0026] Specifically, a rotary seat 309 is welded to the right side of the limit plate 306, and a rotary motor 310 is installed on the top of the rotary seat 309. A rotary shielding plate 311 is arranged inside the rotary seat 309 and is rotatably connected thereto, and the rotary shielding plate 311 forms a rotary structure with the rotary seat 309 via the rotary motor 310. The rotary shielding plate 311 prevents the steel sleeve from tilting to the right when it is lowered. After the lock plate 304 fixes the steel sleeve, the rotary motor 310 is activated, separating the rotary shielding plate 311 from the steel sleeve, allowing the steel sleeve to be propelled to the right.

[0027] Specifically, a sliding roller 312 is installed on the right side of the base 1, and the sliding roller 312 matches the dimensions of the base 1. Multiple sets of sliding rollers 312 are installed to reduce the friction force when the steel sleeve is pushed forward, making operation easier.

[0028] Operating principle: First, the steel sleeve is lowered downward. The bell-shaped opening 307 guides the steel sleeve, then it passes between the limit plates 306 and reaches the specified position. This eliminates the need for manual alignment during the lifting process, avoiding injury to the operator and improving safety. The side plate 308 prevents the steel sleeve from tilting to the left, and the rotating shield plate 311 prevents the steel sleeve from tilting to the right as it descends. Next, the top tube hydraulic cylinder 301 extends and locks the mounting seat 302 to the inside of the steel sleeve. Then, the fixing hydraulic cylinder 303 extends and fixes the locking plate 304 to the inner surface and left side of the steel sleeve, securing the steel sleeve during top tube operation. The L-shaped locking plate 304 prevents the locking plate 304 from getting caught between the steel sleeve and the steel sleeve during top tube operation, which could affect the operation. The packing 305 fits tightly against the steel sleeve, preventing it from slipping, absorbing vibrations within the system and preventing damage to equipment. After the lock plate 304 secures the steel sleeve, the rotary motor 310 is activated, separating the rotary shielding plate 311 from the steel sleeve and propelling the steel sleeve to the right. Next, the top hydraulic cylinder 301 extends further, pushing the steel sleeve into the tunnel. The sliding rollers 312 reduce friction when the steel sleeve is pushed forward, making operation easier.

[0029] The above is merely an embodiment of the present utility model, and detailed descriptions of known specific structures and characteristics are omitted. Those skilled in the art will recognize that the present utility model is not limited to the above embodiment, and may be embodied in other specific forms without departing from the spirit and essential characteristics of the present utility model. Therefore, in all respects, the embodiment is illustrative and not limiting. The scope of the present utility model is limited by the appended claims, not by the above description. Accordingly, all modifications within the meaning and scope of the equivalents of the claims are intended to be included within the scope of the present utility model. Any drawing symbols in the claims should not be construed as limiting the scope of the claims. [Explanation of symbols]
