DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A schematic diagram of the structure of the material lifting device for construction provided by the utility model; Figure 2 For this utility model Figure 1 The enlarged schematic diagram at A in the middle; Figure 3 This is a schematic diagram of the connection between the hanging basket and the limiting mechanism of the utility model; Figure 4 This is the front view of the structure of the utility model; Figure 5The schematic diagram of the connection between the base and the support plate of the utility model. A material lifting device for construction includes a base 1, two L-shaped vertical plates 2 are fixed on the top of the base 1 and are symmetrically distributed, a hanging basket 3 is arranged between the two L-shaped vertical plates 2, two sets of moving wheels 4 are arranged at the bottom of the base 1, and a limiting mechanism is arranged on the L-shaped vertical plates 2. The limiting mechanism is used to improve the stability of the lifting of the hanging basket 3; the limiting mechanism includes a limiting block 201, the bottom end of the limiting block 201 is inserted into the inside of the first plug hole 202 opened on the L-shaped vertical plate 2, and two sets of lifting blocks 301 are fixed on the outside of the hanging basket 3 and are symmetrically distributed. The two sets of lifting blocks 301 are grouped in pairs, and the limiting block 201 extends out of the first plug hole 202. 2 is inserted into the second plug hole 302 opened in the lifting block 301, and two fixed seats 101 are fixed on the top of the base 1 and are symmetrically distributed. The limit block 201 extends out of the second plug hole 302 and is inserted into the slot 102 opened in the fixed seat 101; a through hole 203 is opened in the limit block 201, and a spring 204 is arranged inside the through hole 203. Extrusion plates 205 are fixed at both ends of the spring 204. A fixing plate 206 is fixedly connected to the side of the extrusion plate 205 away from the spring 204, and one end of the fixing plate 206 extends out of the through hole 203 and is inserted into the fixing hole 103 opened in the fixing seat 101.

[0023] Through the above technical solution, the bottom end of the limit block 201 is sequentially passed through the first socket 202 and the second socket 302 and inserted into the slot 102 opened in the fixing seat 101, and through the elastic action of the spring 204, one end of the fixing plate 206 is inserted into the fixing hole 103 opened in the fixing seat 101. The bottom end of the limit block 201 can be fixed inside the slot 102 through the cooperation between the fixing plate 206 and the fixing hole 103. Similarly, the other limit block 201 can be installed and fixed.

[0024] Reference Figure 2 A baffle 207 is sleeved inside the through hole 203 and on the outside of the fixed plate 206. The outside of the baffle 207 is fixedly connected to the inner wall of the through hole 203. The baffle 207 limits the movement of the extrusion plate 205 to prevent the extrusion plate 205 from moving to the outside of the through hole 203 due to the elastic action of the spring 204.

[0025] Reference Figure 1 and Figure 4A motor 104 is provided on one side of the base 1, and a screw rod 105 is fixedly connected to the output end of the motor 104. The thread rotation direction of the left outer surface of the screw rod 105 is opposite to that of the right outer surface. A chamber 106 is opened inside the base 1, and the screw rod 105 extends to the outer side of the chamber 106 and is provided with two thread blocks 107. A rigid rope 108 is connected to the top of the thread block 107, and two first guide pulleys 109 are provided inside the chamber 106. Two symmetrically distributed second guide pulleys 208 are provided on the inner side of the L-shaped vertical plate 2, and the other ends of the rigid rope 108 are respectively connected with the first guide pulley 109 and the second guide pulley 208 and are connected to the top of the hanging basket 3.

[0026] Through the above technical solution, the motor 104 drives the screw rod 105 to rotate, and the rotation of the screw rod 105 causes the two threaded blocks 107 to approach or move away from each other. When the two threaded blocks 107 approach each other, the rigid rope 108 pulls the hanging basket 3 to move upward to lift the building materials. When the two threaded blocks 107 move away from each other, the hanging basket 3 moves downward under the action of the gravity of the hanging basket 3 and the building materials in the hanging basket 3.

[0027] Reference Figure 1 , Figure 4 and Figure 5 A support plate 110 is provided at the bottom of the base 1, two first vertical plates 111 symmetrically distributed in the left and right directions are fixed on the top of the support plate 110, a first sliding rod 112 is fixed between the two first vertical plates 111, and the first sliding rod 112 is slidably connected to two first sliding blocks 113, two second vertical plates 114 symmetrically distributed in the left and right directions are fixed at the bottom of the base 1, a second sliding rod 115 is fixed between the two second vertical plates 114, and two second sliding blocks 116 are slidably connected to the outer side of the second sliding rod 115, and two connecting plates 117 are cross-arranged at the bottom of the base 1, and the two connecting plates 117 are rotatably connected through a rotating shaft 118, and the connecting plates 11 7 is provided with two movable shafts 119, one end of the two movable shafts 119 extends out of the connecting plate 117 and is fixedly connected to the outer side of the first slider 113 and the outer side of the second slider 116 respectively, two third vertical plates 120 are fixed at the bottom of the base 1, a cylinder 121 is fixed to one side of the third vertical plate 120, a push plate 122 is provided between the second vertical plate 114 and the third vertical plate 120, a push rod of the cylinder 121 passes through the third vertical plate 120 and is fixedly connected to one side of the push plate 122, and two push rods 123 are fixed to the other side of the push plate 122, one end of the push rod 123 passes through the second vertical plate 114 and is fixedly connected to one side of the second slider 116.

[0028] Through the above technical solution, the moving wheel 4 is convenient for moving the base 1. When the material is lifted, the top rod of the cylinder 121 drives the push plate 122 and the push rod 123 to squeeze the second slider 116, so that the two second sliders 116 on the second slide bar 115 are close to each other. When the two second sliders 116 are close to each other, the two connecting plates 117 rotate, so that the two first sliders 113 on the first slide bar 112 are close to each other. The support plate 110 moves downward through the rotation of the two connecting plates 117. The downward movement of the support plate 110 puts the base 1 and the moving wheel 4 in a vacant state to prevent the base 1 from being affected by the moving wheel 4 and moving at will during the material lifting process.

[0029] Reference Figure 1 and Figure 4 Two vertical blocks 124 symmetrically distributed on the left and right are fixed at the bottom of the base 1, and a telescopic groove 125 is opened inside the vertical block 124. A limiting plate 126 is arranged inside the telescopic groove 125. A telescopic rod 127 is fixedly connected to the bottom of the limiting plate 126. The telescopic rod 127 extends out of the bottom end of the vertical block 124 and is fixedly connected to the top of the support plate 110. When the support plate 110 moves downward, the telescopic rods 127 in the two vertical blocks 124 move downward, and the downward movement of the support plate 110 is limited by the two telescopic rods 127 to prevent the support plate 110 from tilting when it moves downward, so that the movement of the support plate 110 is more stable.

[0030] The implementation principle of a material lifting device for construction according to an embodiment of the utility model is as follows: by adopting a limiting mechanism, the bottom end of the limiting block 201 is sequentially passed through the first insertion hole 202 and the second insertion hole 302 and inserted into the slot 102 opened in the fixing seat 101, and through the elastic action of the spring 204, one end of the fixing plate 206 is inserted into the fixing hole 103 opened in the fixing seat 101, and the bottom end of the limiting block 201 can be fixed inside the slot 102 through the cooperation between the fixing plate 206 and the fixing hole 103. Similarly, the other limiting block 201 can be installed and fixed, and the up and down movement of the hanging basket 3 is limited by the two limiting blocks 201 to prevent the hanging basket 3 from shaking when it moves up and down, so that the hanging basket 3 has higher stability when moving.
