Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a portable building construction material lifting device. Background Technology

[0002] In the construction process, the transportation and lifting of materials between floors is a common and essential operation, especially in the middle and later stages of high-rise building construction, when large quantities of bricks, mortar, and decorative materials need to be transported to the floors manually or mechanically. Traditional material transportation methods mainly include tower cranes, derrick cranes, and electric winches. However, these methods generally suffer from problems such as bulky structures, complex installation, large space occupation, inconvenience in movement, and poor adaptability, making them unsuitable for construction scenarios with short construction cycles, limited space, or small local work areas.

[0003] Especially at some unfinished building construction sites, where permanent enclosure structures and transportation channels have not yet been installed, existing large material lifting devices are difficult to deploy quickly and move flexibly. Furthermore, their installation and dismantling require significant manpower and are time-consuming. In addition, some simple hoisting devices lack effective protective measures during use, posing safety hazards such as materials slipping or tipping over during lifting, potentially injuring workers or damaging building components. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a portable construction material lifting device. It is a portable material lifting device that can be firmly installed and has the function of preventing material fall, so as to solve the problems of poor adaptability, poor portability and insufficient safety protection in the local area of ​​existing construction sites.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable construction material lifting device includes a J-shaped frame. A vertical beam is welded to the upper part of the J-shaped frame, and a frame hook is provided at one end of the J-shaped frame. A bottom locking rod is inserted and installed inside the frame hook, and a top locking rod is inserted and installed at the top of the vertical beam. The top locking rod and the vertical beam are connected by a threaded connection, and the bottom locking rod and the frame hook are connected by a threaded connection. Both the frame hook and the top locking rod are used to install and fix the J-shaped frame.

[0007] Furthermore, a lifting frame is welded between the vertical beam and the J-shaped frame. A lifting motor is fixed on the upper part of the lifting frame, and a turntable shaft is movably mounted on one end of the lifting frame via a bearing. The turntable shaft and the lifting motor are connected by a V-belt drive. Both ends of the turntable shaft are nested with traction rope turntables, and a hanger traction rope is wound around the outside of the traction rope turntable.

[0008] Furthermore, a material hoist is attached to the bottom of the hoist traction rope.

[0009] Furthermore, a mesh cover frame is fixed to one end of the J-shaped frame, and a protective mesh cover is sewn onto the outer side of the mesh cover frame.

[0010] Furthermore, a support plate is installed on the top of the top locking rod, which is used to increase the contact area with the wall.

[0011] Furthermore, a transfer wheel is provided at the bottom of the frame hook section, and a frame push rod is welded between the J-shaped frame and the vertical beam. The frame push rod and the transfer wheel are used for portable movement of the J-shaped frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a transfer wheel at one end of a J-shaped frame and a frame push rod welded between the frame and the vertical beam, giving the entire device excellent portability and mobility. Construction workers can quickly deploy the device to the edge of a bare building by pushing the frame push rod, solving the problems of bulky structure, complex installation, and inconvenience in moving existing material lifting equipment. It is more adaptable and improves on-site construction efficiency.

[0014] This utility model achieves stable fixation of the device on the edge of a rough building by using the frame hook, bottom locking rod, top locking rod and support plate in combination; the bottom locking rod contacts the roof beam and the top locking rod fits against the ceiling surface through the support plate, which improves the installation stability of the overall device and avoids the problem of displacement or falling off of traditional portable devices under high load or vibration conditions.

[0015] This utility model features a mesh cover frame on one side of a J-shaped frame, with a protective mesh cover sewn onto its outer side. The protective mesh cover automatically unfolds under gravity, covering the material hoisting frame and effectively preventing materials from rolling or splashing during hoisting. This solves the problem of existing simple lifting devices lacking safety protection measures and posing a risk of material falling and injuring people during high-altitude operations.

[0025] like Figure 1 and Figure 2 As shown, the bottom of the traction rope 134 of the gantry is attached to the material gantry 105; the material gantry 105 is composed of a steel frame and has a pre-set material loading platform and guardrail structure inside, which is used to support construction materials and prevent materials from falling; when the traction rope turntable 133 rotates, the traction rope 134 of the gantry is simultaneously extended and retracted, driving the material gantry 105 to move up and down, realizing the lifting and placement of materials.

[0026] like Figure 1 and Figure 2 As shown, a net cover frame 106 is fixed to one end of the J-type frame 101. The net cover frame 106 is used to support the unfolded protective net cover 161. The protective net cover 161 is a tear-resistant nylon mesh structure, and its outer edge is installed on the net cover frame 106 by a sewing process. Before use, the protective net cover 161 is gathered and tied with ropes. Before the material hoisting operation, the ropes are released, and the protective net cover 161 unfolds automatically under the action of gravity. The unfolded protective net cover 161 covers the outer perimeter of the material hoist 105, which can effectively prevent falling materials from splashing outside the work area, thereby avoiding damage to the workers and equipment below.
