Description

Technical Field

[0001] The utility model relates to the technical field of construction ladders, and particularly relates to an automatic door opening device for an intelligent construction ladder. Background Art

[0002] The construction lift is a kind of manned and cargo-carrying construction machinery widely used in various constructions, mainly used for the construction of interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings. In the prior art, the automatic opening and closing function of the construction lift landing door is usually realized by means of devices such as electromagnets, human body infrared sensors and door closers. When a person approaches the landing door, the human body infrared sensor senses the signal and sends it to the control system. After receiving the signal, the control system controls the electromagnet to be energized, so that the electromagnet contacts the middle position at the upper end of the landing door, thereby keeping the landing door in an open state. When a person leaves the landing door, the human body infrared sensor senses the signal again and sends it to the control system. After receiving the signal, the control system controls the electromagnet to be powered off, and at this time the door closer drives the landing door to close automatically. Therefore, most of the commonly used methods for automatically opening and closing doors in the prior art are electrically controlled methods, and the cost is relatively high. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an automatic door opening device for an intelligent construction ladder, which is composed of a mechanical structure and can realize the automatic opening and closing of the construction lift landing door.

[0004] The utility model adopts the following technical solutions:

[0005] An automatic door opening device for an intelligent construction ladder is installed between the discharge door and the landing door of the construction lift, and includes a bump, a cam, a long rod, a baffle and a slider. The landing door is provided with a long strip hole, and the discharge door is provided with an installation groove. The bump is located in the installation groove of the discharge door. The baffle is connected to the lift and is located on one side of the discharge door. The discharge door is provided with a first spring, and one end of the first spring abuts against the bump. The cam is provided with a chute matching the bump. The long rod is arranged on the cam, and one end of the long rod is hinged with a slider, and the slider is slidably matched in the long strip hole.

[0006] Preferably, the chute is a spiral groove arranged on the surface of the cam.

[0007] Preferably, the automatic door opening device has a first state. In the first state, the bump is located in the installation groove of the discharge door, and the bump presses on the first spring. The baffle is located on one side of the discharge door to limit the outward movement of the bump.

[0008] Preferably, the automatic door opening device has a second state. In the second state, the discharge door moves relative to the baffle, the baffle releases the restriction on the bump, and the bump slides in the chute, causing the long rod to rotate and push the landing door open through the slider.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model provides an automatic door opening device for an intelligent construction ladder, including a bump block, a cam, a long rod, a baffle and a sliding block. When working, the discharge door moves relative to the baffle, the baffle releases the restriction on the bump block, the bump block slides in the slide groove, causing the long rod to rotate and push the floor door to open through the sliding block. It is composed of a mechanical structure and can realize the automatic opening and closing of the floor door of the construction elevator. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure, there are a discharge door 1, a layer door 2, a long hole 2-1, a bump block 3, a cam 4, a slide groove 4-1, a long rod 5, a baffle 6, a slide block 7, and a first spring 8. DETAILED DESCRIPTION

[0015] In order to facilitate the understanding of the technical solution of the utility model, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figures 1-4 As shown, an automatic door opening device of an intelligent construction ladder is installed between the discharge door 1 and the floor door 2 of the construction elevator, including a bumper 3, a cam 4, a long rod 5, a baffle 6 and a slider 7. The floor door 2 has a long hole 2-1, and the discharge door 1 is provided with a mounting groove. The bumper 3 is located in the mounting groove of the discharge door 1. The baffle 6 is connected to the elevator and is located on one side of the discharge door 1. The discharge door 1 has a first spring 8, one end of the first spring 8 is against the bumper 3, and the cam 4 has a slide groove 4-1 matching the bumper 3. The long rod 5 is arranged on the cam 4, and one end of the long rod 5 is hinged with a slider 7, and the slider 7 is slidably matched in the long hole 2-1. Among them, the slider 7 is limited in the long hole 2-1, that is, the slider 7 can only slide along the long hole 2-1 and cannot be separated from the long hole 2-1.

[0018] The slide groove 4 - 1 is a spiral groove arranged on the surface of the cam 4 .

[0019] The automatic door opening device has a first state. In the first state, the bump block 3 is located in the installation groove of the discharge door 1, and the bump block 3 presses on the first spring 8. The baffle 6 is located on one side of the discharge door 1 to restrict the outward movement of the bump block 3.

[0020] The automatic door opening device has a second state. In the second state, the discharge door 1 moves relative to the baffle 6, the baffle 6 releases the restriction on the bump block 3, and the bump block 3 slides in the chute 4-1, causing the long rod 5 to rotate and push the landing door 2 open through the slider 7.

[0021] The first state is the state where the landing door 2 is not opened. When the landing door 2 needs to be opened, the discharge door 1 moves upward relative to the baffle 6, the baffle 6 releases the restriction on the bump block 3, and the bump block 3 moves outward under the action of the first spring 8. The bump block 3 slides in the chute 4-1, causing the cam 4 to rotate, thereby driving the long rod 5 to rotate and pushing the landing door 2 open through the slider 7. When the discharge door 1 moves downward relative to the baffle 6, the discharge door 1 drives the bump block 3 to move downward. After the bump block 3 contacts the baffle 6, it retracts into the discharge door 1 under the action of the baffle 6 and compresses the first spring 7. When the bump block 3 passes through the chute 4-1, it drives the cam 4 to rotate. The rotation of the cam 4 drives the long rod 5 to retract, and the long rod 5 pulls the landing door 2 back to close it through the slider 7.

[0022] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as within the protection scope of the present invention.
