Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-7A construction material lifting device includes a bracket 1, which is made of a steel structure; a suitable top height is provided under the premise of ensuring sufficient strength; a support base is arranged at the lower part of the bracket 1, and the bracket 1 is stably installed through the support base.

[0036] A support platform 2 is provided at the top of the bracket 1 to provide a component installation space; a slide rod 3 is provided at the front and rear ends of the support platform 2, and the slide rod 3 is arranged along the left and right directions; a left guide rail 4 and a right guide rail 5 are provided on the slide rod 3; at the same time, a first lifting arm 6 is slidably provided on the left guide rail 4, and a second lifting arm 7 is slidably provided on the right guide rail 5.

[0037] It can be understood that two ear plates are respectively provided at the lower part of the left guide rail 4 and the right guide rail 5 to match the slide rod 3 .

[0038] When in use, the distance between the left guide rail 4 and the right guide rail 5 is adjusted by controlling the movement of the left guide rail 4 and the right guide rail 5 on the slide rod 3, so as to match different widths of the hoisted objects and provide a balanced hoisting state.

[0039] At the same time, the first lifting arm 6 and the second lifting arm 7 can be used simultaneously or individually, and their different extension lengths can be controlled to further control the lifting position and ensure a balanced state.

[0040] In some embodiments, a distance sensor 8 is disposed on each of the left and right sides of the support platform 2 , and the distance sensor 8 measures the distance between the left guide rail 4 and the right guide rail 5 .

[0041] Accordingly, a control box 9 is provided on one side of the bracket 1 , and a display component is provided on the control box 9 , which displays the position distance between the first lifting arm 6 and the second lifting arm 7 .

[0042] Therefore, during operation, the positions of the left guide rail 4 and the right guide rail 5, as well as the distance therebetween, can be accurately understood through the display component of the control box 9, thereby achieving high-precision adjustment and control.

[0043] It can be understood that the measuring end of the distance sensor 8 can be set to face the left guide rail 4, the right guide rail 5, or the first lifting arm 6, the second lifting arm 7; the two distance sensors 8 are relatively facing inward; the installation position of the distance sensor 8 can be set at the upper end or the lower end of the support platform 2.

[0044] In some embodiments, a laser point emitter 10 is vertically disposed at the front end of the first lifting arm 6 and the second lifting arm 7 .

[0045] When in use, as the two booms move, the laser point transmitter 10 emits laser points to the ground; the position of the booms can be accurately understood to match the hoisting and hanging position of the hoisted object; the accuracy of adjustment, as well as the balance and stability of the hoisting can be further ensured.

[0046] In some embodiments, a top rotating shaft 11 is disposed at the front end of the first lifting arm 6 and the second lifting arm 7 , and a counter 12 is disposed on the outer side of the top rotating shaft 11 .

[0047] It can be understood that the counter 12 is connected to the control box 9 for communication; by knowing the number of rotations of the top rotating shaft 11, the winding and loosening lengths of the cable 19 can be known; combined with the cable position in the initial state, the display component of the control box 9 can display the current lifting height and lifting speed, further ensuring the accuracy of the operation.

[0048] In some embodiments, the support platform 2 includes a horizontal bar 201 and a vertical bar 202 .

[0049] The crossbar 201 is arranged on the left and right sides of the top of the bracket 1, the longitudinal rod 202 penetrates the crossbar 201 on both sides and extends outward, and the slide rod 3 is arranged on the inner side of the crossbar 201; the lower part of the crossbar 201 and the longitudinal rod 202 is provided with an oblique support rod.

[0050] In some embodiments, a guide rail driving assembly 13 is disposed below the support platform 2 to provide power to the left guide rail 4 and the right guide rail 5 .

[0051] Specifically, the guide rail driving assembly 13 includes a motor 14 , a screw rod 1301 , and an internal threaded sleeve 1302 .

[0052] An internal thread sleeve 1302 is respectively provided at the lower part of the left guide rail 4 and the right guide rail 5, and the positions of the internal thread sleeves 1302 are staggered; the screw rod 1301 cooperates with the internal thread sleeve 1302, and the two motors 14 are respectively connected to a screw rod 1301 for transmission.

[0053] See also Figure 4 , 5 In this example figure, the internal thread sleeves 1302 of the left guide rail 4 and the right guide rail 5 are respectively located at the front and rear sides of the longitudinal rod 202, and the two screw rods 1301 are matched therewith.

[0054] The motor 14 is arranged on the outside of the support platform 2. Ear plates are arranged on both sides of the lower part of the support platform 2. The screw rod 1301 penetrates the two ear plates.

[0055] In some embodiments, a lifting arm driving assembly 15 is disposed on the upper portion of the support platform 2 to drive the two lifting arms respectively.

[0056] Among them, the lifting arm driving assembly 15 includes a gear plate 1501, a transmission shaft 1502, and a motor 14.

[0057] The toothed plate 1501 is arranged on the upper surface of the first lifting arm 6 and the second lifting arm 7; the transmission shaft 1502 is arranged above the toothed plate 1501 for rotation through two ear plates fixedly connected to the top of the support platform 2; at the same time, the two transmission shafts 1502 are respectively provided with gears 1503 on the left and right halves, and the gears 1503 are meshed with the toothed plate 1501; the two motors 14 are respectively connected to a transmission shaft 1502 for transmission.

[0060] The motor 14 is connected to the transmission shaft 1502 via a belt, and the two motors 14 of the lifting arm driving assembly 15 are respectively arranged on the upper parts of both ends of the longitudinal rod 202.

[0061] In some embodiments, the left guide rail 4 and the right guide rail 5 are T-shaped guide rails, and the first lifting arm 6 and the second lifting arm 7 are clamped on the upper part of the left guide rail 4 and the right guide rail 5 .

[0064] It is understandable that counterweights are provided at the tail ends of the first lifting arm 6 and the second lifting arm 7 according to needs.

[0065] When the present invention is in use, the distance between the left guide rail 4 and the right guide rail 5 is adjusted through the guide rail driving component 13 according to the lifting position width of the required lifting object; during the adjustment, the laser point emitted by the laser point transmitter 10 assists ground personnel in determining the lifting position; during lifting, the display component of the control box 9 obtains the real-time lifting height through the counter 12.

[0066] When necessary, the extension distances of the first lifting arm 6 and the second lifting arm 7 are adjusted, and the position of the lifting point is adjusted to better suit the lifting object.

[0067] In the present invention, the left guide rail 4 and the right guide rail 5 are controlled to adjust the distance between them, match different widths of the hoisted objects, and provide a balanced hoisting state; the first hoisting arm 6 and the second hoisting arm 7 can be used simultaneously or separately, and their different extension lengths can be controlled to further control the hoisting position and ensure a balanced state. A distance sensor 8 is provided to accurately understand the positions of the left guide rail 4 and the right guide rail 5, as well as the distance between them, to achieve high-precision adjustment and control; a laser point transmitter 10 is provided to accurately understand the position of the boom to match the hoisting and hanging position of the hoisted object, further ensuring the accuracy of the adjustment, as well as the balance and stability of the hoisting. A counter 12 is provided to obtain the current hoisting height and hoisting speed, further ensuring the degree of precision in the operation; the motor 14 drives the transmission shaft 1502, and the transmission shaft 1502 is meshed with the tooth plate 1501, and is independently controlled, with greater flexibility.
