Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline lifting devices, and in particular relates to a vertical lifting device for installing an electromechanical pipeline. Background Art

[0002] The construction of modern buildings often involves the installation of overhead pipelines for fire protection, water supply, heating, air conditioning and other systems. The size and weight of the pipelines are often large, and the height to which the pipelines need to be lifted may be high. Therefore, lifting devices are required to assist in lifting the pipelines, so as to save manpower and ensure construction safety.

[0003] The Chinese patent with the publication number CN220564200U discloses a pipeline lifting device, including a fixed frame, a lifting frame, and an electric hoist. The fixed frame is composed of a base frame and a vertical frame. The lifting frame is slidably mounted on the vertical frame, and the electric hoist is fixedly mounted on the base frame. A fixed pulley is provided on the top of the vertical frame. A steel wire rope passes around the fixed pulley and is connected and fixed to the lifting frame. The other end of the steel wire rope is wound on the pulley of the electric hoist. The electric hoist drives the lifting frame to rise and fall by forward and reverse rotation. Two steel pipe brackets are provided on the upper side of the lifting frame, and the pipeline is placed on the steel pipe bracket. The device can be widely used in the installation of overhead pipelines in buildings, and has a simple structure, low production cost, strong practicality, and convenient later maintenance. It can quickly complete the pipeline installation, reduce manpower operations, reduce safety risks, and improve construction efficiency.

[0004] However, in actual use, although the setting of the steel pipe bracket and the clamp can play a role of interception and protection when the pipeline is lifted, since the clamp and the steel pipe bracket are set on the lifting frame, when the workers lift the pipeline through the lifting frame, they need to lift the pipeline to the top of the clamp by manpower first. The process of lifting the pipeline by manpower is more physically demanding and there are certain safety hazards. In addition, the presence of the clamp will also cause certain obstacles to the placement of the pipeline. That is, the above-mentioned device consumes more manpower when used, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a vertical lifting device for installing an electromechanical pipeline, so as to solve the problem that the prior art mentioned above consumes much manpower when used.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical lifting device for installing an electromechanical pipeline, comprising:

[0007] A bottom plate, a placement slot is provided on the bottom plate, a fixing frame is installed in the placement slot, and a lifting mechanism is installed on the bottom plate;

[0008] The lifting plate is abutted in the placement groove, and the lifting plate and the fixed frame are slidably matched, the lifting plate is connected to the lifting mechanism, and the two sides of the top surface of the lifting plate are respectively provided with a clearance groove;

[0009] The limiting mechanism includes two limiting units respectively arranged in two giving way grooves, the limiting unit includes two limiting components symmetrically arranged about the giving way grooves, the limiting components include a vertical plate, a connecting plate, a connecting rod, a baffle and a limiting spring, the vertical plate is installed on the connecting plate, and the vertical plate and the connecting plate are both slidably inserted in the giving way grooves, the connecting plate has an L-shaped shape, and the projection of the bottom edge of the connecting plate on the horizontal plane extends to the outside of the projection of the giving way groove on the horizontal plane, the connecting rod is fixed to the bottom of the lifting plate, and the bottom edge of the connecting plate is slidably sleeved on the connecting rod, the baffle is fixed to the bottom of the connecting rod, and the limiting spring is sleeved on the connecting rod and is located between the connecting plate and the baffle.

[0010] The principle and effect of this technical solution:

[0011] 1. Through the setting of the connecting rod, baffle, limit spring and connecting plate, the connecting plate can slide up and down in the make-away groove, thereby driving the upper vertical plate to slide up and down along the make-away groove, that is, the pipeline only needs to be lifted to the top surface of the bottom plate, and then the vertical plate is driven down to make way for the pipeline to be placed on the lifting plate, and the pipeline can be placed in the limit mechanism. After the downward pressure on the vertical plate is removed, the vertical plate returns to its original position under the rebound force of the limit spring, and then the pipeline is located between the two vertical plates. The vertical plate is used to limit the pipeline laterally, so that the pipeline will not fall from the side when it is lifted (the pipeline can be round or square, and the restriction effect on square pipelines is better)

[0012] 2. By setting limit units on both sides of the limit plate, and the two limit components limit the pipe, it is not easy for the pipe to roll and fall and injure workers after being placed on the lifting plate. By placing the lifting plate in the placement groove, the lifting plate can have a lower upper surface height when it is in the lowest position, so that the pipe can be moved to the lifting plate more conveniently, saving manpower.

[0013] 3. The lifting plate is lifted by the lifting mechanism so that the pipes on the lifting plate reach the specified height of the corridor, thereby completing the lifting of the pipes.

[0014] The utility model is further configured as follows: the limiting assembly also includes an inclined plate, which is obliquely arranged at the bottom of the vertical plate, the top edge of the inclined plate close to one end of the vertical plate is higher than the top edge of the inclined plate away from one end of the vertical plate, the inclined plate is slidably matched with the give way groove, and the inclined plate is located between the two vertical plates.

[0015] The principle and effect of this technical solution: through the setting of the inclined plate, in addition to the vertical plate being able to limit the two sides of the pipeline, the inclined plates on both sides form a V-shaped appearance, which abuts against the bottom surface of the pipeline under the lifting action of the limit spring. The inclined surface of the inclined plate abuts and guides the bottom surface of the pipeline, so that the pipeline has a certain centering guiding force when placed on the lifting plate, and can also have an excellent limiting effect when limiting the circular pipeline, so that the pipeline is less likely to move to the vertical plate during the lifting process, thereby making the limiting effect of the limiting mechanism better.

[0016] The utility model is further configured as follows: the limiting assembly also includes a telescopic rod and a return spring, one end of the telescopic rod is hinged to the side wall of the connecting plate, the other end of the telescopic rod is hinged to the bottom surface of the inclined plate, and the return spring is sleeved on the telescopic rod, and the bottom of the vertical plate is hinged to the top of the connecting plate.

[0017] The principle and effect of the technical solution are as follows: by hingedly connecting the vertical plate and the connecting plate, the vertical plate can drive the inclined plate to rotate relative to the connecting plate, so that when the pipeline moves to the top of the lifting plate, the vertical plate can be driven to make way for the pipeline by abutting, so that workers can choose whether to press or abut to place the pipeline in the limiting mechanism according to actual usage, thereby expanding the flexibility of the device when used, and by setting the telescopic rod and the return spring, the maximum length and minimum length of the telescopic rod limit the rotation angle of the inclined plate relative to the connecting plate, and the rebound force of the return spring drives the inclined plate and the vertical plate to return to their original positions after the pipeline leaves the vertical plate surface, thereby limiting the pipeline.

[0018] The utility model is further configured as follows: a transition plate is rotatably arranged on one side of the bottom plate, the transition plate has a guide sliding surface, and the bottom edge of the transition plate away from one end of the bottom plate abuts against the ground.

[0019] The principle and effect of this technical solution: The setting of the transition plate allows the pipeline to be pushed to the bottom plate by sliding or rolling, and then placed on the lifting plate. The pipeline is lifted by overcoming friction and gravity force. Compared with directly lifting the pipeline, less force is required, thereby saving manpower and facilitating the placement of the pipeline on the bottom plate and the lifting plate.

[0020] The utility model is further configured such that when the lifting plate abuts against the bottom of the placement groove, the top surface of the lifting plate is flush with the top surface of the bottom plate.

[0021] The principle and effect of this technical solution: by making the surface of the lifting plate flush with the top surface of the base plate when placed in the placement groove, the pipeline only needs to be moved to the ground of the base plate to be pushed above the lifting plate, so that the lifting plate can lift the pipeline, thereby reducing the height of the pipeline required to be lifted by manpower and saving manpower.

[0022] The utility model is further configured as follows: the lifting mechanism includes an electric hoist, a fixed pulley and a lifting ring, the electric hoist is fixed on the bottom plate, the lifting ring is fixed on the lifting plate, the fixed pulley is installed on the fixed frame, the movable end of the electric hoist is provided with a steel rope, and the steel rope passes through the fixed pulley and is connected to the lifting ring.

[0023] The principle and effect of this technical solution: the electric hoist controls the contraction of the steel rope, thereby lifting the lifting ring through the steering of the fixed pulley, and the lifting plate is driven to rise and fall through the lifting ring, thereby lifting the pipeline.

[0024] The utility model is further configured as follows: the bottom of the bottom plate is provided with universal wheels.

[0025] The principle and effect of the technical solution: The setting of the universal wheels facilitates the position adjustment and movement of the device in the corridor. BRIEF DESCRIPTION OF THE DRAWINGS
