Abstract
Description
Technical Field
[0001] The utility model relates to the field of pump station gates, in particular to a maintenance gate with a locking support structure. Background Art
[0002] Inspection gates are generally flat gates, which are lifted by gantry cranes or special lifting equipment. In large and medium-sized dams and reservoirs, inspection gates are often underwater for a long time, which aggravates the rust of the gates and other parts of the gates (such as the rust of the slider), making it difficult for the gates to run smoothly in the guide rails, causing the gates to be stuck or stuck during lifting. Therefore, the underwater environment is very unfavorable for the gates, and the gates need to be lifted above the water surface. However, for large and medium-sized dams or reservoirs, under normal circumstances, the lifting equipment is not subjected to force, and the inspection gates fall on the locking device. Patent CN219731883U discloses a locking device for inspecting flat gates, which is mainly achieved by setting a rotating member 31 and a locking member 32, and using the rotation of the rotating member to achieve the connection and disengagement of the rotating member and the locking member, thereby achieving locking and release. However, the locking assembly in the locking device disclosed in the patent is directly subjected to tensile stress, has a short service life, and has low locking safety. Utility Model Content
[0003] The locking components of the locking devices in the prior art are generally directly subjected to tensile stress or compressive stress. Some locking components are even prone to breakage when subjected to stress, resulting in a short service life. Once the breakage problem occurs, the locking is invalid and the locking safety is not high. The present application is a maintenance gate with a locking support structure, which has at least one purpose or at least one aspect that can solve the above problems. The specific technical solutions adopted are:
[0004] An inspection gate with a locking support structure, comprising:
[0005] A gate plate and a slider disposed thereon, wherein at least two sliders are provided, and at least two sliders are symmetrically disposed on the left and right sides of the gate plate, and each slider is provided with a first connecting hole;
[0006] At least two locking support frames are provided, each locking support frame is provided with a second connecting hole, and the at least two locking support frames are correspondingly connected to the at least two sliding blocks through threaded connectors.
[0007] Preferably, the locking support frame is I-shaped, and four first connecting holes and four second connecting holes are respectively arranged. The four first connecting holes are arranged at intervals in the up and down and left and right directions. The four second connecting holes are jointly arranged on one of the flange plates of the I-shaped locking support frame, and the four second connecting holes are arranged on the locking support frame corresponding to the four first connecting holes.
[0008] Preferably, the side of the gate plate has a concave cavity, and the concave cavity has a horizontal reinforcing plate at the position corresponding to the slider. The locking support frame also has an extension portion, which is a U-shaped plate. One end of the U-shaped plate is connected to the flange plate of the locking support frame, and the other end extends into the concave cavity of the gate plate. The upper edge of the U-shaped plate abuts the bottom surface of the horizontal reinforcing plate. A third connecting hole is provided on the U-shaped plate, and a threaded connecting member passes through the first connecting hole, the second connecting hole and the third connecting hole to connect the locking support frame, the U-shaped plate and the slider.
[0009] Preferably, the extension portion and the locking support frame are an integrally formed structure.
[0010] Preferably, the flange plate and the lower edges of the web of the I-shaped locking support frame are wrapped with rubber sleeves.
[0011] Preferably, four sliders are provided, and the four sliders are divided into two slider groups, and the two slider groups are symmetrically arranged on the left and right sides of the gate plate. Each slider group includes two sliders, and the two sliders are symmetrically arranged on the front and rear sides of the gate plate. Four locking support frames are provided, and the four locking support frames are connected to the four sliders through threaded connectors.
[0012] Preferably, a protrusion is vertically provided on the slider, and a flange plate of the locking support frame connected to the slider is vertically provided with a groove, and when the gate plate is locked, the protrusion is located in the groove.
[0013] The utility model provides an I-shaped locking support frame, and detachably connects it to a slider on the gate plate through bolts. When the gate plate needs to be lowered for use, the locking support frame and the slider are disassembled. When the gate plate needs to be raised or lowered above the water surface, the locking support frame is connected to the slider. One of the flange plates of the I-shaped locking support frame is connected to the slider, and the other flange plate is pressed on the ground (or the gate pier) to lock and support the gate plate. The multiple bolt connections not only improve the locking safety, but also cooperate with the extension part to reduce the tensile strength of the lower bolts and the compressive strength of the upper bolts, thereby reducing the direct force on the bolts and extending their service life.

[0019] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0020] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations 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 referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0021] like Figure 1-4 As shown, a maintenance gate with a locking support structure includes a gate plate 2 and a slider 5 arranged thereon. The gate plate 2 is a rectangular plate. At least two sliders 5 are arranged. Just to ensure the balance of the gate plate 2, it is preferred to set the number of sliders 5 to an even number, so that they can be symmetrically arranged on the gate plate 2 to ensure force balance. The at least two sliders 5 are symmetrically arranged on the left and right sides of the gate plate 2. Each slider 5 is provided with a first connecting hole 501 to facilitate the connection of the slider 5 with the locking support frame 6 described below.
[0022] At least two locking support frames 6 are provided, each locking support frame 6 is provided with a second connecting hole, and at least two locking support frames 6 are connected to at least two sliders 5 via threaded connectors, where the threaded connectors can be bolts 7, studs and nuts for connection and locking.
[0023] The detachable connection method of the above-mentioned threaded connector is for easy disassembly, because the inspection gate is generally in two states. One is that when the working gate needs to be inspected, the inspection gate needs to be lowered to temporarily block water. The other is that when the working gate is working normally, the inspection gate needs to be raised and placed above the water surface to avoid it being in an underwater environment to increase its degree of corrosion and reduce its service life. Therefore, the locking support frame 6 is used when the inspection gate is raised and above the water surface to lock it.
[0024] When the inspection gate is located above the water surface, the slider 5 thereon rises to a position close to the gate pier 1 or the ground, connecting the locking support frame 6 to the slider 5, and at the same time, the lower surface of the locking support frame 6 is pressed on the ground or the gate pier 1, thereby achieving the purpose of locking and supporting.
[0025] Furthermore, the locking support frame 6 is I-shaped, and four first connecting holes 501 and second connecting holes are respectively arranged. The four first connecting holes 501 are arranged at intervals in the up and down and left and right directions on the gate plate 2, and the four second connecting holes are jointly arranged on one of the flange plates 601 of the I-shaped locking support frame 6 and are arranged at intervals in the up and down directions on the flange plate 601. The four second connecting holes are connected to the four first connecting holes 501 correspondingly through bolts 7. The reason why it is set as an I-shaped steel plate is that the I-shaped structure combined with its setting angle here can improve its bending strength.
[0026] Furthermore, the side of the gate plate 2 has a concave cavity 3, and the concave cavity 3 has a horizontal reinforcing plate 4 corresponding to the slider 5. The slider 5 is arranged at the left and right edges of the gate plate 2. The locking support frame 6 also has an extension portion 603, and the extension portion 603 is a U-shaped plate. One end of the U-shaped plate is connected to the flange plate 601 of the locking support frame 6, and the other end extends into the concave cavity 3 of the gate plate 2. The upper edge of the U-shaped plate abuts against the bottom surface of the horizontal reinforcing plate 4. A third connecting hole is provided on the U-shaped plate, and the threaded connecting member passes through the first connecting hole 501, the second connecting hole and the third connecting hole to connect the locking support frame 6, the U-shaped plate and the slider 5. When the locking support frame 6 is connected to the gate plate 2, the upper bolt 7 is subjected to compressive stress and shear force at the same time, and the lower bolt 7 is subjected to tensile stress and shear force at the same time. However, due to the existence of the extension part 603, the tensile stress and compressive stress on the bolt 7 will be partially borne by the extension part 603, that is, it is converted into pressure at the edge of the extension part 603 and the gate plate 2. Since the effective area between the extension part 603 and the gate plate 2 is large, the force on the bolt 7 is reduced.
[0027] Furthermore, in order to improve the strength of the extension portion 603 , the extension portion 603 and the locking support frame 6 are an integrally formed structure.
[0028] Furthermore, in order to protect the ground or the gate pier 1, the lower edges of the flange plate 601 and the web 602 of the I-shaped locking support frame 6 are wrapped with rubber sleeves 8. After the locking support frame 6 and the extension portion 603 are cast and formed, the rubber sleeve 8 can be put on them after rough processing, or the rubber can be heated and melted, and the I-shaped locking support frame 6 can be immersed in the rubber liquid, and then cooled to form a rubber layer to form the rubber sleeve 8.
[0029] In one embodiment, in order to improve the locking support strength and balance, four sliders 5 are provided, and the four sliders 5 are divided into two slider groups. The two slider groups are symmetrically arranged on the left and right sides of the gate plate 2. Each slider group includes two sliders 5. The two sliders 5 are symmetrically arranged on the front and rear sides of the gate plate 2. Four locking support frames 6 are provided, and the four locking support frames 6 are connected to the four sliders 5 through threaded connectors.
[0030] Furthermore, a protrusion 502 is vertically provided on the above-mentioned slider 5. When the slider 5 slides in the guide rail at the reservoir gate, the protrusion 502 is located in the guide rail. The purpose of setting the protrusion 502 is to limit the gate plate 2 to the left and right to reduce the left and right shaking of the gate plate 2. The flange plate 601 of the locking support frame 6 connected to the slider 5 is vertically provided with a groove 604. When the gate plate 2 is locked, the protrusion 502 is located in the groove 604, so that the flange plate 601 of the locking support plate can be tightly attached to the slider 5, thereby improving the stability of the locking support plate and reducing its shaking.
[0031] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
[0032] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
