[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 10 As shown:

[0037] A large drainage pump transfer system in a water collection well, comprising a transfer device consisting of a bracket 1, a bearing plate 2 and an auxiliary lifting frame 3, wherein the bearing plate 2 is used to carry and fix the drainage pump, a bracket 1 for the transfer device to move is fixedly installed on the outer side of the bearing plate 2, and an auxiliary lifting frame 3 is also provided for lifting the front end of the transfer device;

[0038] The pulley 4 arranged at a fixed position is used to control the pulling direction of the rope 5, so that the transfer device is pulled by the rope 5 to move on the stairs and the bearing surface.

[0039] In this scheme, the road leading to the water collection well is generally narrow, uneven and has multiple corners. Ordinary transfer equipment is not convenient for transporting water pumps. Large drainage pumps are heavy and difficult to transport manually, especially when there are steps to climb, which increases the difficulty of transporting drainage pumps. The traditional method is semi-mechanized transportation, which requires manual participation. During the transportation process, it is easy to cause the drainage pump to be scratched and collided, and the safety of the drainage pump and personnel cannot be guaranteed.

[0040] The drainage pump is transported by a transfer device composed of a bracket 1, a load-bearing plate 2 and an auxiliary lifting frame 3. The pulley 4 is fixed to the wall at the corner with an expansion bolt. One end of the rope 5 passes through several pulleys 4 and is connected to a winch. The other end of the rope 5 is connected to the transfer device. The rope 5 is wound up by the winch to pull the transfer device to move, thereby realizing the transportation of the drainage pump. The bracket 1 is a crawler 104-type walking structure. In the transition stage of the transfer device moving from the ground to the climbing stairs, the auxiliary lifting frame 3 is used to lift the front end of the transfer device, which is conducive to moving the transfer device from the ground to the climbing stairs.

[0041] The bracket 1 is set in an inverted trapezoidal shape with inclined ends. This shape of the bracket 1 improves its ability to cross obstacles. However, relying solely on the structure of the bracket 1, there is still a large resistance when moving from the horizontal ground to the stairs. When the traction transfer device moves, the inclined portion of the bracket 1 will contact the corner of the stairs. At this time, the front end of the bracket 1 needs to overcome the friction between the bracket 1 and the corner of the stairs when it is lifted. Since the contact area between the corner of the stairs and the bracket 1 is small and the pressure is large, the surface of the bracket 1 is easily damaged when the traction bracket 1 moves. As the front end of the bracket 1 is lifted, the bracket 1 The inclined portion of the front end of the bracket 1 will become more and more perpendicular to the ground, and the closer the inclined portion of the front end of the bracket 1 is to the vertical state, the smaller the angle between the inclined portion of the front end of the bracket 1 and the vertical portion of the step will be, and the force required to pull the bracket 1 will be greater. The end of the auxiliary lifting frame 3 is supported against the angle between the step and the ground. When traction is applied, the front end of the transfer device will be supported by the auxiliary lifting frame 3 and lifted, so that the inclined portion of the bracket 1 will not directly contact the corner of the step, avoiding the problem of direct traction causing increasing effort and damage to the bracket 1 caused by the corner of the step.

[0042] In an optional embodiment, the bracket 1 includes a retaining plate 101, a plurality of road wheels 103 are rotatably connected between the two retaining plates 101, the two retaining plates 101 are fixedly connected via a connecting plate 102, the outer sides of the plurality of road wheels 103 are rotatably connected to tracks 104, and the outer sides of the retaining plates 101 are fixedly connected to a fixed bracket 105.

[0043] In this embodiment, the two retaining plates 101 are fixedly connected into a whole through the connecting plate 102, the road wheel 103 is used for the rotation support of the track 104, and the fixed bracket 105 is used for the fixed installation of the supporting plate 2. The bracket part of one pressure wheel 106 is fixedly connected to the top surface of the fixed bracket 105, and the bracket part of the other pressure wheel 106 is fixedly connected to the supporting plate 2. The pressure wheel 106 is used to maintain the basic shape of the track 104 when it rotates.

[0044] In an optional embodiment, a plurality of limit plates 201 are fixedly connected to the top surface of the supporting plate 2, a through groove is provided at the top of the limit plate 201, a support plate 202 is fixedly connected to the outer side of the front end of the supporting plate 2, and a hanging hole 203 is provided at one end of the support plate 202.

[0045] In this embodiment, the through groove opened on the limit plate 201 can be used for the passage of the strap, and the strap and the limit plate 201 can better fix the drainage pump on the supporting plate 2. The hanging hole 203 opened on the support plate 202 is used for connecting the rope 5. The support plate 202 can also be used to fix the bracket 302.

[0046] In an optional embodiment, the bottom of the carrying plate 2 is fixedly connected to the top of the fixing bracket 105 .

[0047] In this embodiment, the provision of two groups of brackets 1 can better fix the carrying plate 2, improve the stability of the transfer device during movement, and also improve the steering effect of the transfer device.

[0048] In an optional embodiment, the auxiliary lifting frame 3 includes a lifting rod 301, a retaining bracket 302 and a roller 303 rotatably connected to the end of the lifting rod 301. The retaining bracket 302 is fixed relative to the transfer device. When the front end of the transfer device is lifted, the lifting rod 301 is rotatably set relative to the retaining bracket 302. After the lifting of the front end of the transfer device is completed, the lifting rod 301 is slidably set relative to the retaining bracket 302.

[0049] In this embodiment, by pressing the end of the lifting rod 301 against the position between the step and the ground, the front end of the traction transfer device can be lifted, so that the bottom of the bracket 1 can be pressed on the step. However, when the traction continues, the lifting rod 301 will hinder the movement of the transfer device. Therefore, the active movement of the lifting rod 301 is required to avoid the occurrence of this problem. Fig.10 As shown in the orientation, in the initial state, the end of the lifting rod 301 is tilted to the lower left, and as the traction work continues, since the end position of the lifting rod 301 is fixed in this state, the lifting rod 301 will rotate counterclockwise around the retaining bracket 302 and lift the front end of the transfer device. While the front end of the transfer device is lifted, the transfer device will move to the left, and after the lifting rod 301 rotates counterclockwise around the retaining bracket 302 to the maximum limit, the lifting rod 301 will slide relative to the retaining bracket 302, that is, the lifting rod 301 moves upward, thereby preventing the lifting rod 301 from affecting the continued movement of the transfer device.

[0050] In an optional embodiment, one end of the retaining bracket 302 is fixedly connected to the retaining shell 304, and the interior of the retaining shell 304 is rotatably connected to a driven block 307, the inner side of the driven block 307 is slidably connected to the outer surface of the lifting rod 301, and when the top end of the lifting rod 301 is located inside the retaining shell 304, the top end surface of the lifting rod 301 can slideably cooperate with the inner wall surface of the retaining shell 304.

[0051] In this embodiment, the retaining shell 304 is cylindrical, and the inner wall surface of the retaining shell 304 is rotatably connected to a driven block 307. The inner side of the driven block 307 cooperates with the lifting rod 301 to enable the lifting rod 301 to rotate or slide better on the inner side of the retaining shell 304. Figure 6 As shown, when the top end of the lifting rod 301 is located inside the retaining shell 304 , the top end surface of the lifting rod 301 can slide with the inner wall surface of the retaining shell 304 , thereby realizing the rotation of the lifting rod 301 around the center rod 308 .

[0052] In an optional embodiment, a movable groove 306 for the lifting rod 301 to move is opened at one end of the retaining shell 304, and a through groove 305 for the top end of the lifting rod 301 to pass through is also opened at one end of the retaining shell 304.

[0053] In this embodiment, the movable slot 306 is provided to enable the lifting rod 301 to rotate around the central rod 308 , and when the top end of the lifting rod 301 is aligned with the passing slot 305 , the lifting rod 301 can pass through the passing slot 305 .

[0054] In an optional embodiment, a widened head 3011 is provided at the top end of the lifting rod 301 , and the width of the through slot 305 is greater than the width of the movable slot 306 .

[0055] In this embodiment, by providing a widened head 3011 at the top of the lifting rod 301, the top of the lifting rod 301 can have a larger contact area with the inner wall surface of the retaining shell 304 when sliding, thereby obtaining better rotation and support effects. The width of the groove 305 is greater than the width of the movable groove 306, that is, the top of the lifting rod 301 is wider, and the rest of the lifting rod 301 is relatively narrow, which can reduce the weight and cost of the lifting rod 301.

[0056] In an optional embodiment, one end of the retaining bracket 302 is fixedly connected to a center rod 308, and the center rod 308 extends through the follower block 307 to the inner side of the slide groove of the lifting rod 301. The outer surface of the center rod 308 is adapted to the slide groove opened in the lifting rod 301. The inner side of the slide groove opened in the lifting rod 301 is slidably connected to a spring seat 309, and the spring seat 309 is magnetically connected to the center rod 308. A tension spring 3010 is fixedly connected between the bottom of the slide groove of the lifting rod 301 and the inner side of the spring seat 309.

[0057] In this embodiment, the cooperation of the holding shell 304, the driven block 307 and the center rod 308 can enable the top end of the lifting rod 301 to be located in the internal space of the holding shell 304 and to be able to rotate stably. When the top end of the lifting rod 301 is aligned with the through slot 305, the elastic force of the tension spring 3010 can drive the lifting rod 301 to move, that is, the end of the lifting rod 301 moves toward the center rod 308, and the spring seat 309 can rotate relative to the center rod 308, and the two are magnetically connected. The magnetic force between the center rod 308 and the spring seat 309 is greater than the elastic force of the tension spring 3010, so that the center rod 308 and the spring seat 309 can still maintain contact when they rotate relative to each other.

[0058] The transfer device itself is not heavy, so when it is first used, it is turned over 90 degrees or 180 degrees, which makes it easier to push the lifting rod 301 to overcome the elastic force of the tension spring 3010 and move the top of the lifting rod 301 to the inside of the holding shell 304, that is, Figure 2 In the state shown, the transfer device is then turned back, and then the drainage pump is installed on the supporting plate 2. Through the provided rollers 303, when the transfer device moves on the ground, there will not be a large resistance between the end of the lifting rod 301 and the ground, which makes it easy to pull the transfer device to the stairs.

[0059] In an optional embodiment, the two sides of the bottom end of the retaining bracket 302 are fixedly connected to the fixed bracket 105 and the support plate 202 respectively. This arrangement allows the lifting rod 301 to rotate at multiple angles without interference, and can improve the installation and connection strength of the auxiliary lifting frame 3.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
