DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] Embodiment one

[0032] As shown in the figure, in combination with the wall-attached seat 2, a building machine lifting mechanism of the present application comprises a sleeve frame 1, a first movable part 3, a second movable part 4, a linkage assembly 5, a first telescopic mechanism 6, a second telescopic mechanism 7, and a guide rail 9. Figure 1 Figure 3 The sleeve frame 1 extends along the vertical line and moves along the vertical line at both ends. The sleeve frame 1 is far away from the wall surface, and the sleeve frame 1 does not contact the wall-attached seat 2.

[0033] The wall-attached seat 2 is arranged on the wall surface along the vertical line, and the blocking pin 21 is arranged on the wall-attached seat 2. The hook is arranged in the middle of the wall-attached seat 2.

[0034] The guide rail 9 extends along the vertical line and moves along the vertical line at both ends. The guide rail 9 can be connected with or separated from the wall-attached seat 2. The guide rail 9 is provided with a plurality of clamping grooves, and the guide rail 9 is hung on the hook of the wall-attached seat 2 through the clamping grooves.

[0035] The guide rail 9 extends along the vertical line and moves along the vertical line at both ends. The guide rail 9 can be connected with or separated from the wall-attached seat 2. The guide rail 9 is provided with a plurality of clamping grooves, and the guide rail 9 is hung on the hook of the wall-attached seat 2 through the clamping grooves.

[0036] ​The first telescopic mechanism 6 is a hydraulic telescopic cylinder, and is arranged on the sleeve frame 1. The two ends of the first telescopic mechanism 6 are connected with the guide rail 9 and the sleeve frame 1 respectively, and the first telescopic mechanism 6 is used to drive the guide rail 9 or the sleeve frame 1 to move. Specifically, the two ends of the first telescopic mechanism 6 are provided with reversing boxes respectively, and the bottom end of the first telescopic mechanism 6 is fixedly arranged in the middle of the sleeve frame 1. When the lifting mechanism needs to climb, first, the reversing box at the bottom end of the first telescopic mechanism 6 is released from the sleeve frame 1, and the reversing box at the top end is locked with the guide rail 9, then the first telescopic mechanism 6 is elongated to make the guide rail 9 rise and be hung on the adjacent wall seat 2, then the reversing box at the bottom end of the first telescopic mechanism 6 is locked with the sleeve frame 1, and the reversing box at the top end is released from the guide rail 9, and finally the first telescopic mechanism 6 is retracted to make the sleeve frame 1 rise, so that the lifting mechanism completes a rising action.

[0037] The first movable part 3 and the second movable part 4 are arranged at the two ends of the sleeve frame 1. The end face of the second movable part 4 facing the wall is provided with a gap 401, and the second movable part 4 is hung on the stop pin 21 through the gap 401. The second movable part 4 is used to limit the horizontal shaking of the sleeve frame 1.

[0038] The second telescopic mechanism 7 is also a hydraulic telescopic cylinder, and the two ends of the second telescopic mechanism 7 are connected with the sleeve frame 1 and the second movable part 4 respectively and are used to drive the second movable part 4 to move relative to the sleeve frame 1.

[0039] The linkage assembly 5 is arranged on the sleeve frame 1 and is used to link the first movable part 3 and the second movable part 4.

[0040] When the above technical scheme is adopted, in order to make the second movable part 4 automatically realize the action of being hung on or separated from the stop pin 21, when the sleeve frame 1 moves and the first movable part 3 abuts against the stop pin 21 of one of the wall seats 2, the second movable part 4 is moved towards the adjacent wall seat 2 through the linkage assembly 5, is hung on the corresponding stop pin 21, and limits the horizontal movement of the sleeve frame 1 relative to the wall seat 2; and when the sleeve frame 1 moves and the first movable part 3 is away from the stop pin 21 of the wall seat 2, the second movable part 4 can be moved away from the wall seat 2 through the linkage assembly 5 and separated from the stop pin 21. More specifically, when the first telescopic mechanism 6 is retracted and drives the sleeve frame 1 to rise, the second telescopic mechanism 7 is retracted and drives the second movable part 4 to move away from the wall seat 2 through the linkage assembly 5; when the sleeve frame 1 rises to the position where the first movable part 3 abuts against one of the stop pins 21, the first telescopic mechanism 6 stops driving the sleeve frame 1 to rise and starts to elongate, and the second telescopic mechanism 7 is elongated and drives the second movable part 4 to be hung on the adjacent stop pin 21 through the linkage assembly 5.

[0041] A method for using the lifting mechanism of the building machine, the lifting mechanism of the embodiment is adopted, and the method comprises the following steps:

[0042] Step one, the first telescopic mechanism 6 is extended and makes the guide rail 9 rise, at the same time, the second telescopic mechanism 7 is extended and makes the second movable part 4 hang on the corresponding stop pin 21 through the linkage assembly 5.

[0043] Step two, the guide rail 9 rises until the first telescopic mechanism 6 is extended to the maximum, and the guide rail 9 is hung on the attached wall seat 2, then the first telescopic mechanism 6 is retracted and makes the sleeve frame 1 rise, at the same time, the second telescopic mechanism 7 is retracted and makes the second movable part 4 disengage from the corresponding stop pin 21 through the linkage assembly 5.

[0044] Step three, the sleeve frame 1 rises until the first movable part 3 abuts against the corresponding stop pin 21, and the step one is repeated.

[0045] Embodiment two

[0046] On the basis of embodiment one, since the first telescopic mechanism 6 and the second telescopic mechanism 7 are both hydraulic cylinders, the linkage action of the first movable part 3 and the second movable part 4 can be realized by controlling the hydraulic output state of the two telescopic mechanisms.

[0047] Specifically, as shown in Figure 1 , in combination with Figure 5 , Figure 6 and Figure 7 , the linkage assembly 5 includes a hydraulic delivery system 51, a solenoid valve 52, a first pipeline 53, a second pipeline 54, a relay 55 and a trigger switch 56.

[0048] Among them, the hydraulic delivery system 51 is used for storing, outputting and recycling hydraulic medium and has a delivery end 501, a first return end 502 and a second return end 503. The hydraulic delivery system 51 includes a hydraulic storage tank and a delivery pump connected to the delivery end 501.

[0049] The solenoid valve 52 has an inlet 504, a first return port 505, a second return port 506, a first delivery port 507 and a second delivery port 508. The inlet 504 is in communication with the delivery end 501, and the first return port 505 and the second return port 506 are in communication with the first return end 502 and the second return end 503, respectively. The solenoid valve 52 in the case is a five-way solenoid valve.

[0050] The first telescopic mechanism 6 has a first inlet 601 and a second inlet 602, and the second telescopic mechanism 7 has a third inlet 701 and a fourth inlet 702.

[0051] One end of the first pipeline 53 is in communication with the first delivery port 507, and the other end of the first pipeline 53 is in communication with the first inlet 601 and the third inlet 701 at the same time.

[0052] The second pipeline 54 has one end connected with the second delivery port 508, and the other end connected with the second inlet 602 and the fourth inlet 702.

[0053] The relay 55 is electrically connected with the electromagnetic valve 52 and has a normally closed contact and a normally open contact. The relay 55 is a conventional electrical component, and thus the specific structure and working principle thereof are not described in detail.

[0054] The trigger switch 56 is arranged on the first movable part 3. The trigger switch 56 is also a conventional electrical component, and thus can be regarded as a structural component having the trigger switch 56 inside the first movable part 3. When the first movable part 3 abuts against the stop pin 21 and moves backward, the structural component having the trigger switch 56 inside the first movable part 3 is turned on, so that the trigger switch 56 is turned on and off.

[0055] The electromagnetic valve 52 has a first state and a second state, and the first movable part 3 abuts against the stop pin 21 and switches the electromagnetic valve 52 from the first state to the second state. It should be noted that the electromagnetic valve 52 controls the extension and retraction state of the hydraulic telescopic cylinder by controlling the flow direction of hydraulic oil, which is a mature technology widely used. Thus, the specific structure of the electromagnetic valve 52 and the principle of how the electromagnetic valve 52 switches the flow direction of the hydraulic oil by switching the state are not described in detail, but only the function of the electromagnetic valve 52 and the result of the function are described in the present application.

[0056] In the initial state, the trigger switch 56 is turned off, and the relay 55 is connected with the normally closed contact and makes the electromagnetic valve 52 in the first state. When the electromagnetic valve 52 is in the first state, the inlet 504 is connected with the first delivery port 507, the first return port 505 is connected with the second delivery port 508, and the first telescopic mechanism 6 and the second telescopic mechanism 7 are retracted at the same time. Thus, when the sleeve frame 1 is lifted by the retraction of the first telescopic mechanism 6, the second movable part 4 is separated from the stop pin 21 by the retraction of the second telescopic mechanism 7 and does not hinder the lifting of the sleeve frame 1.

[0057] When the first movable part 3 abuts against the stop pin 21, the trigger switch 56 is turned on, the relay 55 is connected with the normally open contact, and the electromagnetic valve 52 is switched to the second state. When the electromagnetic valve 52 is in the second state, the inlet 504 is connected with the second delivery port 508, the second return port 506 is connected with the first delivery port 507, and the first telescopic mechanism 6 and the second telescopic mechanism 7 are extended at the same time. Thus, when the sleeve frame 1 stops lifting, the first telescopic mechanism 6 is extended and drives the guide rail 9 to lift, and the second movable part 4 is hung on the stop pin 21 by the extension of the second telescopic mechanism 7 and limits the horizontal shaking of the sleeve frame 1.

[0058] The use method of the lifting mechanism of the building machine, which adopts the lifting mechanism of the embodiment, comprises the following steps:

[0059] Step 1: The first telescopic mechanism 6 extends and the guide rail 9 rises. At the same time, the second telescopic mechanism 7 extends through the linkage component 5 and the second movable part 4 is hooked onto the corresponding stop pin 21. At this time, the solenoid valve 52 is in the second state.

[0060] Step 2: The guide rail 9 rises until the first telescopic mechanism 6 extends to its maximum length, and the guide rail 9 is hung on the wall mount 2. Then, the solenoid valve 52 is manually operated to switch to the first state, the first telescopic mechanism 6 retracts and the sleeve 1 rises, and at the same time, the second telescopic mechanism 7 retracts through the linkage component 5 and the second movable part 4 disengages from the corresponding stop pin 21.

[0061] Step 3: The sleeve 1 rises until the first movable part 3 abuts against the corresponding stop pin 21, so that the solenoid valve 52 switches to the second state and Step 1 is repeated.

[0062] Example 3

[0063] Based on Example 1, such as Figure 1 As shown, combined with Figure 2 and Figure 4 It also includes lever 8.

[0064] The second telescopic mechanism 7 is hinged at both ends to the sleeve 1 and the second movable part 4.

[0065] The pull rod 8 is mounted on the sleeve 1 and has a telescopic function. One end of the pull rod 8 is fixed to the second movable part 4 and the other end is hinged to the sleeve 1. The axis of the pull rod 8 intersects the axis of the second telescopic mechanism 7.

[0066] The lever 8 serves to guide the second telescopic mechanism 7 to move the second movable part 4 telescopically. At the same time, when the second movable part 4 is attached to the stop pin 21, the lever 8 also serves to hold the sleeve 1 to prevent it from swaying horizontally.

[0067] Example 4

[0068] Based on Embodiment 1, it should be noted that during actual construction, the sleeve 1 will only rise and not fall. Therefore, in order for the first movable part 3 to abut against the stop pin 21 and to disengage from the stop pin 21 as the sleeve 1 rises,

[0069] like Figure 1 As shown, combined with Figure 2 The end face of the first movable part 3 facing the wall is provided with a wedge-shaped surface 301. When the sleeve 1 rises, the wedge-shaped surface 301 contacts the stop pin 21. The stop pin 21 moves relative to the first movable part 3 along the wedge-shaped surface 301 and moves the first movable part 3 toward the sleeve 1 until the sleeve 1 stops rising.

[0070] Example 5

[0071] On the basis of the embodiment four, when the first movable part 3 is separated from the stop pin 21 with the lifting of the sleeve frame 1, the first movable part 3 needs to be reset, therefore, the slide rod 10 and the elastic member 11 are further included.

[0072] The slide rod 10 is arranged on the sleeve frame 1 and moves horizontally relative to the sleeve frame 1. One end of the slide rod 10 is fixed to the first movable part 3 and the other end extends away from the wall surface.

[0073] The elastic member 11 can be a spring, therefore, the elastic member 11 has the ability of elastic stretching and rebounding. One end of the elastic member 11 is fixed to the end of the slide rod 10 away from the wall surface and the other end is fixed to the sleeve frame 1. When the first movable part 3 abuts against the stop pin 21, the first movable part 3 retreats and elastically stretches the elastic member 11. After the first movable part 3 is separated from the stop pin 21, the elastic member 11 rebounds and pulls the first movable part 3 to reset.

[0074] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
