Description

Technical Field

[0001] The invention relates to the technical field of glass installation, in particular to a glass lifting and moving device for building construction engineering. Background Art

[0002] Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials. It is widely used in buildings, fish tanks, lenses and other fields;

[0003] Glass has the characteristics of windproof and light-transmitting, but its disadvantage is that it is heavy. In order to save manpower and facilitate installation, it is often necessary to use a glass lifter for building construction projects to raise the glass to a specified height for installation;

[0004] At present, the glass lifters and movers for building construction projects on the market are too simple. They only have a lifting function and are unable to adjust the lifted glass to a vertical or appropriate angle, resulting in unstable installation and easy damage. The vacuum suction cup is an important component for the glass lifter and mover for building construction projects to grab the glass. According to the use standard, more than four vacuum suction cups are often required. At present, the vacuum suction cups are all operated individually, which is time-consuming and labor-intensive and inconvenient for grabbing the glass. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Example 1

[0028] See also Figure 1-2In an embodiment of the present invention, a glass lifting and moving device for building construction projects includes a base 1 and four universal wheels 2, the four universal wheels 2 are respectively installed at the four corners of the lower surface of the base 1, and the universal wheels 2 are provided with mechanical brakes for moving the device, and further include: a lifting mechanism 3 is installed on the left side of the upper surface of the base 1, an angle adjustment mechanism 4 is installed on the right side of the lifting mechanism 3, and positioning mechanisms 5 are installed at both the front and rear ends of the right side of the angle adjustment mechanism 4;

[0029] The lifting mechanism 3 includes a slide bar 31, a top plate 32, a first screw rod 33, a lifting plate 34 and a first crank 35. There are two slide bars 31, which are respectively installed at the front and rear ends of the left side of the upper surface of the base 1, and limit the lifting plate 34, so that the lifting plate 34 can move up and down. The top plate 32 is installed at the top of the slide bar 31. One end of the first screw rod 33 is rotatably installed at the center position of the left side of the upper surface of the base 1 through a bearing, and the other end is rotatably installed with the top center position of the top plate 32 through a bearing. When the first screw rod 33 rotates clockwise or counterclockwise, the thread rotation force drives the lifting plate 34 to move up and down. The lifting plate 34 can be slidably sleeved on the outer wall of the slide bar 31, and the center position is screwed with the outer wall of the first screw rod 33. The first crank 35 is installed at the top of the first screw rod 33.

[0030] The angle adjustment mechanism 4 includes a bracket 41, a sleeve 42, a second screw 43, a support rod 44 and a second crank 45. The bracket 41 is rotatably installed at the top center position of the right side wall of the lifting plate 34 through a pin shaft to support the first support plate 51. The sleeve 42 is rotatably installed at the front bottom end of the lifting plate 34 through a pin shaft to support and fix the second screw 43. The second screw 43 is screwed to the inner wall of the sleeve 42. When the second screw 43 rotates clockwise or counterclockwise, it can drive the right side of the bracket 41 to swing downward or upward. One end of the support rod 44 is rotatably sleeved on the right end of the second screw 43, and the other end is rotatably installed with the front end of the bracket 41 through a pin shaft. The support rod 44 and the second screw 43 are in a straight line to ensure that the second screw 43 has the ability to rotate along its own axis. The second crank 45 is installed at the left end of the second screw 43.

[0031] The positioning mechanism 5 includes a first support plate 51, a driving assembly 52, a second support plate 53 and a fixing assembly 54. The first support plate 51 is installed at the right end of the bracket 41, the driving assembly 52 is installed at the center position of the first support plate 51, and the second support plate 53 is installed at the right end of the first support plate 51. There are at least two fixing assemblies 54, which are equidistantly installed on the right side of the second support plate 53 from top to bottom, and the left side is connected to the right side of the driving assembly 52.

[0032] Furthermore, the right side of the bracket 41 protrudes vertically from the right side of the base 1 . When the base 1 moves toward the glass installation location, the glass picked up by the suction cup 542 can reach the installation point first to avoid being blocked by the bracket 41 .

[0033] Further, such as Figure 3-4 As shown, the driving assembly 52 includes a rotating drum 521, a slide groove 522, a traction rod 523, a limiting rod 524, a handle 525 and a mounting plate 526. The rotating drum 521 is rotatably installed at the left center position of the first support plate 51, and the rotating drum 521 can rotate on its own. The outer wall of the rotating drum 521 is provided with a slide groove 522. The traction rod 523 can be slidably inserted into the inner cavity of the rotating drum 521 to pull the piston rod 544 to move left and right. The limiting rod 524 is installed on the left side of the outer wall of the traction rod 523 and is inserted into the slide groove 522. The limiting rod 524 is cylindrical and uses its own curved surface to facilitate sliding in the slide groove 522. There are two handles 525, which are installed on the left end of the outer wall of the rotating drum 521 in opposite directions. The mounting plate 526 is installed on the right end of the traction rod 523.

[0034] Furthermore, the slide groove 522 is divided into three sections, the middle section is an inclined groove, and the front and rear sections are flat grooves. When the slide groove 522 rotates clockwise or counterclockwise, the middle section can squeeze the limit rod 524 to move left and right. When the limit rod 524 enters the flat groove, it can remain stationary.

[0035] Further, such as Figure 5 As shown, the fixing assembly 54 includes a piston cylinder 541, a suction cup 542, a piston 543 and a piston rod 544. The piston cylinder 541 is installed on the right side wall of the second support plate 53, and the suction cup 542 is installed on the right end of the outer wall of the piston cylinder 541. The suction cup 542 is used to adsorb the glass. If necessary, liquid can be applied to the surface of the suction cup 542 to improve its adsorption. The piston 543 can be slidably inserted into the right end of the inner cavity of the piston cylinder 541. By moving the piston 543 to the left, the gas in the suction cup 542 can be extracted to form a pressure difference with the atmospheric pressure, so that the glass is fixed on the suction cup 542. One end of the piston rod 544 is installed on the left end of the piston 543, and the other end is connected to the right side wall of the mounting plate 526.

[0036] Furthermore, the right side walls of the plurality of suction cups 542 are all on the same plane, so that the plurality of suction cups 542 can all contact with the glass and act on the glass at the same time.

[0037] How it works

[0038] Step 1: Rotate the first crank 35 clockwise or counterclockwise to cause the first screw 33 to rotate clockwise or counterclockwise. Under the limiting effect of the slide bar 31, the thread rotation force of the first screw 33 can drive the lifting plate 34 to move upward or downward, thereby realizing the ascent or descent of the angle adjustment mechanism 4 and the positioning mechanism 5.

[0039] Step 2: When picking up, let the suction cup 542 fit with the glass, rotate the handle 525 counterclockwise, the slide groove 522 rotates counterclockwise, and the limit rod 524 moves out of the flat groove of the slide groove 522. Then, with the help of the inclined groove of the slide groove 522, the slide groove 522 squeezes the limit rod 524 to move to the left, prompting the mounting plate 526 to pull multiple piston rods 544 to move left, and the piston 543 absorbs the gas in the suction cup 542, thereby gradually making the pressure in the suction cup 542 less than the atmospheric pressure, so that the atmospheric pressure presses the glass on the suction cup 542 until the limit rod 524 slides to the flat groove at the other end, and the limit rod 524 stays at the current position, realizing the glass picking up, and the suction cup 542 does not need to be operated separately, saving time and effort, and facilitating the fixing of the glass;

[0040] Step three, when adjusting the glass angle, rotate the second crank handle 45 clockwise or counterclockwise to cause the second screw 43 to rotate clockwise or counterclockwise, and the second screw 43 moves to the left or right, thereby causing the bracket 41 to swing downward or upward, thereby changing the angle of the glass and installing the glass as required and firmly.

[0041] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
