Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for building construction, and in particular relates to a hoisting device used for building construction. Background Art

[0002] The common hoisting equipment used in construction currently has a general structure consisting of a fixed frame, a hoisting motor, a rope, and a hook. Various building materials are tied and fixed and then hung on the hook, and then the hoisting motor reels the rope to achieve the basic hoisting effect.

[0003] On the other hand, existing safer lifting equipment will add anti-sway structures to the hooks to ensure that the construction materials go straight up and down as much as possible to avoid hitting the surrounding environment or on-site operators.

[0004] For example, a Chinese utility model patent with authorization announcement number CN220467394U and authorization announcement date 2024.02.09 discloses a material hoist for construction, including a mounting seat, a support column fixedly connected to the top of the mounting seat, a cross bar fixedly connected to the support column, a sliding groove provided at the bottom of the cross bar, a sliding block slidably connected in the sliding groove, a driving motor arranged in the fixed frame, a roller fixedly connected to the output end of the driving motor, a lifting rope movably connected to the roller, a pulley installed at the bottom of the extension plate, a folding rod installed at the bottom of the extension plate below the pulley, a counterweight plate fixedly connected to the bottom of the folding rod, one end of the lifting rope passes around the pulley and passes through the folding rod and the counterweight plate in sequence, one end of the lifting rope is located at the bottom of the counterweight plate and fixedly connected to a hook, and a clamping component for clamping long materials such as pipes is provided on the counterweight plate.

[0005] The material hoist in this utility model patent has the following advantages: the hoisting rope does not shake during the lifting process of the material, the material can be kept moving upward at a stable and uniform speed, and the safety of the entire device body is improved.

[0006] However, in actual use, the material hoist still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] 1. Its folding rod structure completely limits the shaking of the lifting rope. Although it is very safe, it is impossible to directly pull the lifting goods horizontally, making the unloading operation relatively troublesome;

[0008] 2. The weight of the entire lifting structure is all pressed on the engaging position between the slider and the sliding groove. The size of this position is small and it is difficult to support a large weight. Therefore, the slider is easy to break and the entire lifting structure is easy to fall, which is very dangerous.

[0009] So to sum up, there is an urgent need for a structurally reinforced lifting equipment with appropriate anti-sway strength for lifting goods and convenient for horizontal pulling and unloading of goods, so as to be used for lifting various building materials such as cement and pipes at the construction site.

[0010] The utility model provides a hoisting device for building construction, which can be arranged on a bottom plate with a column, a horizontal plate, a hoisting motor, a rope, a hook, a pull rope unit for emergency unloading, an initial adjustment sleeve unit, a limit rod unit, and a counterweight reinforcement unit, so that:

[0011] 1. When lifting the cargo, the operator can appropriately and relatively slightly pull the emergency unloading dual-purpose pull rope unit to avoid a large shake of the cargo. After lifting to the required height, the operator can then pull the emergency unloading dual-purpose pull rope unit relatively significantly, making the unloading operation relatively convenient.

[0012] 2. The lifting motor is pressed on the entire horizontal plate through the initial adjustment sleeve unit, rather than being clamped through a relatively small structure, so the lifting motor is not easy to fall.

[0013] The technical solution adopted by the utility model to solve the above-mentioned problems is: a lifting equipment for construction, the structure of which includes a base plate, a column, a cross plate, a lifting motor, a rope, and a hook, and also includes an emergency unloading dual-purpose pull rope unit arranged on the hook and used to pull the hook laterally, an initial adjustment sleeve unit sleeved on the cross plate and used to install the lifting motor, a limit rod unit arranged on the cross plate and connected to the emergency unloading dual-purpose pull rope unit and used to block the initial adjustment sleeve unit, and a counterweight reinforcement unit arranged on the base plate.

[0014] A further preferred technical solution is that the emergency unloading dual-purpose pull rope unit includes a connecting rod arranged between the rope and the hook, a fixed block arranged on the connecting rod, and a pull rope with two ends respectively arranged on the fixed block and the limit rod unit, the length of which is greater than the rope and is used to pull the hook laterally.

[0015] A further preferred technical solution is that the emergency unloading dual-purpose pull rope unit also includes a transverse pulling ring arranged on the connecting rod, connected to the rope, and used to pass through the pulling hook.

[0016] A further preferred technical solution is that the initial adjustment sleeve unit comprises a rectangular frame which is sleeved on the transverse plate and has the lifting motor disposed on its upper surface.

[0017] A further preferred technical solution is that: a reinforcing inclined plate is further provided on the upright column and the horizontal plate; and the initial adjustment sleeve unit further comprises a fracture which is provided on the bottom plate of the rectangular frame and is used to pass through the reinforcing inclined plate.

[0018] A further preferred technical solution is that the limiting rod unit includes a threaded groove arranged on the upper surface of the transverse plate, and a screw rod arranged on the threaded groove and connected to the pull rope and used for blocking and limiting the rectangular frame.

[0019] A further preferred technical solution is that: the number of the limit rod units is 2, which are respectively arranged at two sides of the initial adjustment sleeve unit.

[0020] A further preferred technical solution is that: the number of the thread grooves is 5-10; the initial adjustment sleeve unit also includes an initial fixing socket arranged on the top plate of the rectangular frame and used for connecting the thread grooves.

[0021] A further preferred technical solution is that the counterweight reinforcement unit includes a diagonal plate arranged on the base plate and the column, a counterweight block arranged on the base plate, a socket arranged on the base plate, and a mud-use plug rod arranged on the socket.

[0022] A further preferred technical solution is that the counterweight reinforcement unit also includes a slot provided on the muddy ground insertion rod and used for inserting the pulling hook before use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0037] As attached Figure 1-8 As shown, a lifting equipment for construction, the structure includes a base plate 11, a column 12, a transverse plate 13, a lifting motor 14, a rope 15, and a hook 16, and also includes an emergency unloading dual-purpose pull rope unit 1 arranged on the hook 16 and used to pull the hook 16 laterally, an initial adjustment sleeve unit 2 sleeved on the transverse plate 13 and used to install the lifting motor 14, a limit rod unit 3 arranged on the transverse plate 13 and connected to the emergency unloading dual-purpose pull rope unit 1 and used to block the initial adjustment sleeve unit 2, and a counterweight reinforcement unit 4 arranged on the base plate 11.

[0038] In this embodiment, the bottom plate 11, the column 12 and the horizontal plate 13 are fixedly connected and made of steel. The lifting motor 14, the rope 15 and the hook 16 are connected in sequence, and the cargo B is first hung on the hook 16, and then the lifting motor 14 is turned on and the rope 15 is rolled up until the cargo B reaches the required height, and the lifting operation is completed.

[0039] The subsequent unloading operation is: use the pulling hook a to hook and pull the emergency unloading dual-purpose pulling rope unit 1 horizontally, so that the cargo b is close to the bottom plate 11. At this time, the lifting motor 14 can unwind the rope 15 as needed until the cargo b falls on the bottom plate 11 and the rope 15 is loose. At this point, the entire unloading operation is completed.

[0040] When the rope 15 is rolled up, the operator can always hold the emergency unloading dual-purpose pull rope unit 1 to perform required, appropriate, and empirical lateral pulling to reset the greatly swinging cargo b, so that the rope 15 is as vertical as possible and the cargo b is as straight up and down as possible.

[0041] The functional characteristics of the initial adjustment sleeve unit 2 are: before lifting, it can slide and adjust to the desired position on the horizontal plate 13, thereby improving the practicality of the lifting device. During lifting, due to the relatively large pressure, it will not slide on the horizontal plate 13, and even if the pull hook a pulls the emergency unloading dual-purpose pull rope unit 1 horizontally, it will not pull the initial adjustment sleeve unit 2.

[0042] In addition, the functions of the limit rod unit 3 include at least: first, when the lifting equipment is idle, it prevents the initial adjustment sleeve unit 2 from accidentally sliding and falling together with the lifting motor 14; second, it prevents the pull rope of the emergency unloading dual-purpose pull rope unit 1 from falling to the ground, but the middle part of the pull rope hangs down, forming a roughly U shape, otherwise the pull rope will easily trip on-site construction workers.

[0043] Finally, the main function of the counterweight reinforcement unit 4 is to balance the weight of the cargo b to prevent the lifting equipment from tipping toward the side of the transverse plate 13 .

[0044] The emergency unloading dual-purpose pull rope unit 1 includes a connecting rod 101 arranged between the rope 15 and the hook 16, a fixing block 102 arranged on the connecting rod 101, and a pull rope 103 whose two ends are respectively arranged on the fixing block 102 and the limiting rod unit 3, and the pull rope 103 is longer than the rope 15 and is used to pull the hook 16 laterally.

[0045] In this embodiment, the main function of the fixing block 102 is to serve as a counterweight for the hook 16 so that the hook 16 does not swing significantly when being lowered alone.

[0046] Among them, during the rising process of the hook 16, the bending amplitude of the pull rope 103 becomes larger and larger, and vice versa, the hook 16 is lowered and the pull rope 103 is straightened. During the whole process, the operator can touch and hold the pull rope 103, and pull it to reset when the hook 16 swings greatly, so as to ensure that the cargo b goes straight up and down as much as possible.

[0047] The emergency unloading dual-purpose pull rope unit 1 further includes a lateral pulling ring 104 which is arranged on the connecting rod 101, connected to the rope 15, and used to pass through the pulling hook a.

[0048] In this embodiment, if the pulling hook a is directly used to hook the hook 16, it is relatively easy to accidentally hook the cargo b and pull it down, which is very dangerous. If the pulling hook a is directly used to hook the rope 15, there will be a lot of wear between the two, which is also to be avoided.

[0049] Therefore, the main function of the lateral pulling ring 104 is to provide a safe and simple hooking position for the pulling hook a. The lateral pulling ring 104, the connecting rod 101 and the hook 16 are integrally formed and made of steel.

[0050] The initial adjustment sleeve unit 2 includes a rectangular frame 201 which is sleeved on the transverse plate 13 and has the lifting motor 14 disposed on its upper surface.

[0051] In this embodiment, the inner length and width of the rectangular frame 201 are slightly larger than the length and width of the cross-sectional rectangle of the horizontal plate 13, so that the former is not easy to shake significantly on the latter.

[0052] The upright column 12 and the horizontal plate 13 are further provided with a reinforcing inclined plate 5 ; the initial adjustment sleeve unit 2 further comprises a cutout 202 which is provided on the bottom plate of the rectangular frame 201 and is used for passing through the reinforcing inclined plate 5 .

[0053] In this embodiment, the disadvantage of the break 202 is that the structural strength of the rectangular frame 201 is slightly reduced, but the advantage is that the reinforcement inclined plate 5 is allowed to be installed, and the sliding area of ​​the rectangular frame 201 will not be restricted by the reinforcement inclined plate 5.

[0054] The former has a minor influence, while the latter has the advantages of the structural reinforcement of the horizontal plate 13 and the unrestricted sliding area of ​​the rectangular frame 201, which are relatively more important. Therefore, the fracture 202 can be opened selectively.

[0055] The limiting rod unit 3 includes a thread groove 301 disposed on the upper surface of the transverse plate 13 , and a screw rod 302 disposed on the thread groove 301 , connected to the pull rope 103 , and used for blocking and limiting the rectangular frame 201 .

[0056] In this embodiment, the depth of the thread groove 301 is within 40% of the thickness of the horizontal plate 13, which cannot significantly reduce the structural strength of the horizontal plate 13. The blocking and limiting effect of the screw rod 302 on the rectangular frame 201 is only required to take effect when the hoisting device is not in use, so the blocking and limiting strength does not need to be large.

[0057] In addition, the material of the fixing block 102 is rubber, which can be connected to the pull rope 103 when it is cast and solidified, and the other end of the pull rope 103 can be tied and connected to the screw rod 302.

[0058] There are two limit rod units 3 , which are respectively arranged at two sides of the initial adjustment sleeve unit 2 .

[0059] In this embodiment, the first structural mode of the limit rod unit 3 is: the number of the thread groove 301 and the screw rod 302 are both 2, which are located in pairs on both sides of the rectangular frame 201 to prevent the rectangular frame 201 from sliding and falling when not in use, or from colliding sharply with the column 12 after sliding.

[0060] At this time, there are two limit rod units 3 , and they have no interaction relationship with the rectangular frame 201 .

[0061] The number of the thread grooves 301 is 5-10; the initial adjustment sleeve unit 2 further includes an initial fixing socket 203 which is arranged on the top plate of the rectangular frame 201 and is used to connect the thread grooves 301 .

[0062] In this embodiment, the second structural mode of the limit rod unit 3 is: the number of the thread grooves 301 is 5-10, but the number of the screw rods 302 is still 2, and the idle thread grooves 301 cooperate with the initial fixing sockets 203 and the existing ordinary straight rods to further prevent the rectangular frame 201 from accidentally sliding when the lifting equipment is in operation.

[0063] It does not matter whether the straight rod is screwed to the thread groove 301 , and a high insertion accuracy is not required, as long as the rectangular frame 201 is properly clamped.

[0064] At this time, it is one of the limit rod units 3 and interacts with the rectangular frame 201 .

[0065] The counterweight reinforcement unit 4 includes a diagonal plate 401 arranged on the base plate 11 and the column 12, a counterweight block 402 arranged on the base plate 11, a socket 403 arranged on the base plate 11, and a mud plug rod 404 arranged on the socket 403.

[0066] In this embodiment, both ends of the inclined plate 401 are fixedly connected, the counterweight block 402 is made of bricks and stones, and the mud floor plugging rod 404 is made of steel.

[0067] When the hoisting device is used on a cast ground, the mud ground insertion rod 404 cannot be inserted downward and is idle, but when used on a mud ground, the mud ground insertion rod 404 can be inserted downward, and together with the inclined plate 401 and the counterweight block 402, the installation stability of the entire hoisting device is improved, making it less likely to tip over. In other words, the hoisting device has a larger safe lifting weight.

[0068] The counterweight reinforcement unit 4 further includes a slot 405 disposed on the muddy ground insertion rod 404 and used for inserting the pulling hook a before use.

[0069] In this embodiment, it does not matter whether the slot 405 passes through the muddy ground insertion rod 404. It can reduce the weight of the muddy ground insertion rod 404 and also serve as a placement position for the pulling hook a when it is idle.

[0070] In other words, the mud floor inserting rod 404 can be a solid rod with a groove or a straight tube. Moreover, whether the mud floor inserting rod 404 is inserted into the mud floor or not does not affect the idle storage function of the pulling hook a on the slot 405, ensuring that the pulling hook a is not easily lost and is easy to take.

[0071] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
