Description

Technical Field

[0001] This utility model relates to the technical field of machine back drawer control seat, specifically a surface contact machine back drawer control seat. Background Technology

[0002] A condensing extraction turbine is a type of steam turbine that can generate electricity and provide heat simultaneously. In a condensing extraction turbine, a portion of the steam is extracted from the intermediate stage of the turbine and supplied to users for heating. The remaining steam continues to perform work within the turbine and is eventually discharged into the condenser for cooling. This design allows the unit to provide heat energy while generating electricity, achieving cascaded energy utilization.

[0003] In normal circumstances, back-extraction retrofitting is carried out to enhance the heating capacity of the original extraction condensing unit. However, the manual control panel is laborious and inflexible, requiring a lever, and the control panel screw often bends, causing inconvenience in adjusting the unit load, easily creating safety hazards, and increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a surface-contact back-mounted control seat to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface-contact back-mounted control seat, comprising a connecting rod assembly and a rotating partition assembly. The bottom of the connecting rod assembly is connected to the rotating partition assembly, and the bottom of the rotating partition assembly is provided with a connecting shaft bracket. Furthermore, a connecting pile assembly is vertically installed at the bottom of the connecting shaft bracket. The rotating partition assembly comprises a partition seat body, a connecting groove, a fixing block, a limiting block, a docking pile, a docking insertion hole, and a movable slide groove. The bottom of the partition seat body is provided with a connecting groove, and a fixing block is provided on one side of the top of the partition seat body. A limiting block is inserted on the side of the partition seat body away from the fixing block, and a docking pile is provided at the end of the limiting block near the partition seat body. Simultaneously, movable slide grooves are provided on the left and right surfaces of the partition seat body near the docking pile.

[0006] Furthermore, the connecting rod assembly includes an operating screw body, a thrust bearing seat, and a combined sliding seat. The top end of the operating screw body is provided with a thrust bearing seat, and the bottom end of the operating screw body is provided with a combined sliding seat.

[0007] Furthermore, the main body of the partition seat and the fixing block are fixedly connected, and the outer surface structure of the docking pile matches the inner surface structure of the docking hole.

[0008] Furthermore, the main body of the control screw is slidably connected to the interior of the movable slide groove via a combined sliding seat, and the combined sliding seat and the main body of the control screw are integrally formed.

[0009] Furthermore, the connecting shaft frame includes a main frame, a connecting shaft body, and a docking groove. The connecting shaft body is horizontally installed in the middle of the upper end of the main frame, and the docking groove is provided on the bottom surface of the main frame.

[0010] Furthermore, the partition seat body is connected to the connecting shaft body using a slotted embedded structure, and the partition seat body can be adjusted to swing left and right with the connecting shaft body as the center.

[0011] Furthermore, the connecting pile assembly includes a support pile, a first assembly seat, and a second assembly seat. The first assembly seat is provided at the top of the connecting pile assembly, and the support pile is provided at the bottom of the support pile.

[0012] Furthermore, the first and second combination seats are provided with holes for bolt installation at the four opposite corners, and the internal surface structure of the mating groove matches the top surface structure of the first combination seat.

[0013] This utility model provides a surface-contact back-mounted control seat, which has the following advantages:

[0014] 1. This utility model addresses the issue that conventional screw drives in the back-drawing control unit, which involve surface contact and high resistance, are prone to drying and scaling when lubricated due to the high ambient temperature, leading to even greater resistance. Therefore, the transmission method is modified to utilize a thrust bearing seat, based on the working principle of the electric door. This structural design minimizes unnecessary structural resistance. Furthermore, the original control unit screw moves in a fixed vertical linear motion while the back-drawing rotating partition moves in an arc, causing the screw transmission force to shift and making operation difficult. To address this, a horizontal sliding groove is created on the control unit panel, and a sliding groove is also provided inside the upper part of the partition seat body. This ensures the control screw body remains vertically stressed within the rotating partition assembly under varying loads. Additionally, a limiting block is installed on one side of the partition seat body using a connecting pile and a connecting hole. This ensures the stability of the connection between the connecting rod assembly and the rotating partition assembly while facilitating structural disassembly and maintenance.

[0015] 2. In this utility model, when reducing the heating load and pressing down the main body of the control screw, the conventional connection between the hook end face of the main body of the control screw and the back-pull rotating partition is a line contact, which can easily cause the partition seat body to slide out and the bent screw to jam. Based on the characteristic that the contact body of the partition seat body is cylindrical, the bottom structure of the partition seat body is changed to a semi-circular arc-shaped moving slide groove structure. This allows the partition seat body to be connected to the main body of the connecting shaft body through a slotted embedded structure. This structure creates a surface contact, making the operation more stable and reliable. In addition, the support pile can be structurally connected to the bottom of the main frame above and the medium-pressure hydraulic motor below using the first and second combination seats at the upper and lower ends, respectively. This allows for good structural modularity and facilitates structural disassembly and maintenance. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 5As shown, a surface-contact back-mounted control seat includes a connecting rod assembly 1 and a rotating partition assembly 2. The bottom of the connecting rod assembly 1 is connected to the rotating partition assembly 2, and the bottom of the rotating partition assembly 2 is provided with a connecting shaft bracket 3. A connecting pin assembly 4 is vertically installed on the bottom of the connecting shaft bracket 3. The rotating partition assembly 2 includes a partition seat body 201, a connecting groove 202, a fixing block 203, a limiting block 204, a docking pin 205, a docking insertion hole 206, and a movable slide groove 207. The bottom of the partition seat body 201 has a connecting groove 202, and a fixing block 203 is provided on one side of the top of the partition seat body 201. A limiting block 204 is installed on the side of the partition seat body 201 away from the fixing block 203, and a docking pin 205 is provided at one end of the limiting block 204 near the partition seat body 201. Meanwhile, movable slide grooves 207 are provided on the left and right surfaces of the partition seat body 201 near the docking pin 205. The connecting rod assembly 1... The system includes a control screw body 101, a thrust bearing seat 102, and a combined sliding seat 103. The top of the control screw body 101 is provided with the thrust bearing seat 102, and the bottom of the control screw body 101 is provided with the combined sliding seat 103. The partition seat body 201 and the fixed block 203 are fixedly connected. The outer surface structure of the docking pile 205 matches the inner surface structure of the docking hole 206. The control screw body 101 is slidably connected to the inside of the movable slide groove 207 through the combined sliding seat 103. The combined sliding seat 103 and the control screw body 101 are integrally structured. By changing the transmission method to use the thrust bearing seat 102 for transmission in accordance with the working principle of the electric door, unnecessary structural resistance problems can be reduced as much as possible. At the same time, a movable slide groove 207 is opened inside the upper end of the partition seat body 201, so that the control screw body 101 can maintain vertical force in the rotating partition assembly 2 under different loads.

[0024] like Figures 1 to 5As shown, the connecting shaft frame 3 includes a main frame 301, a connecting shaft body 302, and a docking groove 303. The connecting shaft body 302 is horizontally installed in the middle of the upper end of the main frame 301, and the docking groove 303 is provided on the bottom surface of the main frame 301. The partition seat body 201 is connected to the connecting shaft body 302 by means of the connecting groove 202 using a slotted embedded structure. The partition seat body 201 can be adjusted by swinging left and right with the connecting shaft body 302 as the center. The connecting pile assembly 4 includes a support pile 401, a first combination seat 402, and a second combination seat 403. The first combination seat 402 is provided at the top of the connecting pile assembly 4. The bottom end of the support pile 401 is provided with a support pile 401. The four diagonal corners of the first combination seat 402 and the second combination seat 403 are provided with holes for bolt installation. The internal surface structure of the mating groove 303 matches the top surface structure of the first combination seat 402. Based on the characteristic that the contact body of the partition seat body 201 is cylindrical, the bottom structure of the partition seat body 201 is changed into a semi-circular arc-shaped sliding groove 207 structure. This allows the partition seat body 201 to be connected and combined with the connecting shaft body 302 by using a slotted embedded structure. This structure forms a surface contact, making the operation more stable and reliable.

[0025] In summary, as Figures 1 to 5 As shown, when using the back-mounted control seat of the machine in contact with the surface, the entire device is first connected and combined with the upper structural component using the control screw body 101 at the top of the control screw body 101. At the same time, the connecting pile assembly 4 is connected and combined with the first combination seat 402 and the second combination seat 403 at the upper and lower ends of the support pile 401, respectively, with bolts, and structurally combined with the upper and lower ends of the main frame 301, respectively, and with the lower medium-pressure hydraulic motor, and connected and combined with the docking groove 303.

[0026] During use, the connecting groove 202 and the connecting shaft body 302 horizontally set at the upper end of the main frame 301 are interlocked to connect the rotating partition assembly 2 and the connecting shaft frame 3. When it is necessary to separate the operating screw body 101 connected to the moving slide 207 by the thrust bearing seat 102 from the partition seat body 201, it is only necessary to pull the limiting block 204 out from the docking hole 206 by the docking post 205, so as to achieve quick separation between the connecting rod assembly 1 and the rotating partition assembly 2.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
