Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace front equipment, in particular to a hydraulic striking machine replacement device. Background Art

[0002] The blast furnace taphole opening machine is a crucial piece of equipment required to open the taphole every time a blast furnace taps iron. A high-quality taphole opening is crucial for efficient and cost-effective tapping, and the performance and efficiency of the blast furnace taphole opening machine directly impact the normal operation of the blast furnace. The hydraulic impact machine, a core component of the blast furnace taphole opening machine, ensures that its stability during operation directly affects the continuity of blast furnace ironmaking production. If a hydraulic impact machine malfunctions during operation, it is crucial to effectively, quickly, and safely replace it, improving maintenance efficiency, reducing labor intensity, and shortening maintenance time to enhance blast furnace production efficiency.

[0003] Announcement No. CN203923231U provides a quick-replacement device for a blast furnace opening machine striking machine, which consists of a bracket and a bracket seat. The structure of the bracket is that the front and rear brackets that match the striking machine body are set on the seat plate. The front and rear brackets are plate-shaped brackets with grooves on the top. The bottom surface of the groove of the front bracket is arc-shaped, and the groove set on the top of the rear bracket is a rectangular groove. In this solution, the front and rear brackets are plate-shaped brackets, and their structural strength is not enough to support the load required by the striking machine. When used for a long time or subjected to high pressure, the bracket may be deformed or even damaged, and thus can no longer provide effective support; and the groove structure designed on the top of the plate makes it easy for the striking machine to move back and forth and tip over during movement, and the stability of the striking machine during movement cannot be guaranteed, and it cannot play an effective limiting role; at the same time, this structure is not convenient for the striking machine to be centered during installation. Summary of the Invention

[0004] In response to the problems existing in the existing technology, the utility model provides a hydraulic striker replacement device, which effectively prevents the striker from shaking or tilting during movement, ensures that the striker remains in a horizontal state, avoids damage or safety risks caused by tilting, and also facilitates the installation and alignment of the hydraulic striker without excessive adjustment and calibration.

[0005] The utility model is implemented as follows: a hydraulic impact machine replacement device includes a bracket for supporting the hydraulic impact machine, a first limiting groove and a second limiting groove on the upper end surface of the bracket, the first limiting groove is adapted to the front end base structure of the hydraulic impact machine, the second limiting groove is adapted to the rear end base structure of the hydraulic impact machine, a sinking portion is provided on the end surface of the bracket between the first limiting groove and the second limiting groove, the sinking depth of the sinking portion is less than the groove depth of the first limiting groove and the second limiting groove, the first limiting groove, the sinking portion and the second limiting groove form a stepped limiting structure; the lower end surface of the bracket is provided with a square steel pipe for forklift forks to extend into.

[0006] Furthermore, two square steel tubes are provided, and the two square steel tubes are symmetrically arranged on both sides of the vertical center line of the bracket.

[0007] Furthermore, the distance between the outer end face of the square steel tube and the side end face of the bracket is 650 mm.

[0008] Furthermore, the groove depths of the first limiting groove and the second limiting groove are 15 mm, and the sinking depth of the sunken portion is 5 mm.

[0009] Furthermore, the bracket is a rectangular plate, and the specifications of the bracket are 2000×500×35 mm.

[0010] The advantages and technical effects of the present invention are as follows: due to the adoption of the above technical solution, the hydraulic striker can be firmly supported on the bracket, effectively preventing shaking or tilting that may occur during movement; the stepped limiting structure further enhances the stability of the hydraulic striker, ensuring that the striker remains in a horizontal state, avoiding damage or safety risks caused by tilting; and at the same time, it is convenient for the installation and alignment of the hydraulic striker; during installation, the striker only needs to be placed in the limiting structure to easily achieve alignment without excessive adjustment and calibration.

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0016] like Figure 1 and Figure 2 As shown, the present application provides a hydraulic hammer replacement device, comprising a bracket 1 for supporting the hydraulic hammer 3. Specifically, the bracket 1 is a rectangular plate with dimensions of 2000×500×35 mm. The upper end surface of the bracket 1 has a first limiting groove 1-1 and a second limiting groove 1-2. The first limiting groove 1-1 mates with the front base structure of the hydraulic hammer 3, while the second limiting groove 1-2 mates with the rear base structure of the hydraulic hammer 3. A sunken portion 1-3 is provided on the end surface of the bracket 1 between the first limiting groove 1-1 and the second limiting groove 1-2. The sunken portion 1-3 has a smaller depth than the first and second limiting grooves 1-1 and 1-2. Specifically, the first and second limiting grooves 1-1 and 1-2 have a depth of 15 mm, while the sunken portion 1-3 has a depth of 5 mm. The first limiting groove 1-1, the sunken portion 1-3, and the second limiting groove 1-2 form a stepped limiting structure.

[0017] The lower end of the bracket 1 is provided with a square steel tube 2 for the forks of a forklift 4 to penetrate. Two square steel tubes 2 are provided, symmetrically arranged on either side of the vertical centerline of the bracket 1. Specifically, the distance between the outer end of the square steel tube 2 and the side end of the bracket 1 is 650 mm.

[0018] When the hydraulic hammer 3 needs to be disassembled and installed, the hydraulic hammer 3 is first supported by the bracket 1, the front end base of the hydraulic hammer 3 is placed in the first limit groove 1-1, and the rear end base of the hydraulic hammer 3 is placed in the second limit groove 1-2, and a forklift is inserted into the square steel pipe 2 under the bracket 1 for replacement and movement.

[0019] Due to the adoption of the above technical solution, the hydraulic hammer 3 can be firmly supported on the bracket 1, effectively preventing shaking or tilting that may occur during movement. The stepped limiting structure further enhances the stability of the hydraulic hammer 3 and ensures that the hammer remains in a horizontal state, avoiding damage or safety risks caused by tilting. At the same time, it also facilitates the installation and alignment of the hydraulic hammer 3. During installation, you only need to place the hammer into the limiting structure to easily achieve alignment without excessive adjustment and calibration.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
