Description

Technical Field

[0001] The utility model relates to the field of hoists, and more specifically to a direct-connected mobile hoist. Background Art

[0002] Hoists are used in various large-scale water supply and drainage, water conservancy and hydropower projects. They are used to control the lifting of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing. Generally, they include hydraulic hoists, winch hoists, gantry cranes, handwheel hoists, electric hand hoists, hand-cranked hoists, screw hoists, double-hanging hoists, etc.

[0003] After some gates are controlled to close or open by a hoist, they will maintain this state for a long time. Therefore, the hoist can be removed and moved to another gate for control. However, most of the existing hoists are heavy in weight and not easy to move, thus affecting the use. Summary of the Utility Model

[0004] The utility model provides a direct-connected mobile hoist, which is easy to move.

[0005] The technical solution adopted by the utility model to solve the above problems is as follows:

[0006] A direct-connected mobile hoist includes a frame, and a winding roller rotatably mounted on the frame. A power motor is installed on the frame, and a speed reducer is installed between the power motor and the winding roller. Transverse shafts are installed at both the front and rear ends of the frame. Support plates are provided at both ends of each transverse shaft, and rollers are rotatably mounted at the lower ends of each support plate.

[0007] The transverse shaft is rotatably connected to the frame. A round seat is provided in the middle of the transverse shaft, a locking hole is provided on the round seat, and locking mechanisms are provided at the corresponding positions of both ends of the frame and the round seat.

[0008] The locking mechanism includes a through-frame slidably penetrating through the frame. An insertion post is provided at the end of the through-frame close to the transverse shaft.

[0009] The end of the insertion post close to the transverse shaft is round-headed.

[0010] A chamfer is provided at the end of the locking hole.

[0011] A spring is provided between the through-frame and the frame to make the through-frame press tightly against the round seat.

[0012] A baffle is provided at the end of the through-frame far from the transverse shaft.

[0013] A pulling hole is provided on the baffle.

[0014] A rubber layer is provided on the outer surface of the roller.

[0015] Mounting holes are provided at the four corners of the frame. Brief Description of the Drawings

[0022] frame 1; winding roller 2; speed reducer 3; power motor 4; horizontal shaft 5; support plate 6; roller 7; round seat 8; locking hole 9; through-frame 10; insertion post 11; spring 12; baffle 13. Specific implementation manners

[0023] The following is described in conjunction with Figures 1-6 for illustration:

[0024] A direct-connected mobile hoist includes a frame 1 and a winding roller 2 rotatably mounted on the frame 1. A power motor 4 is mounted on the frame 1, and a speed reducer 3 is mounted between the power motor 4 and the winding roller 2. Both front and rear ends of the frame 1 are provided with horizontal shafts 5, and both ends of each horizontal shaft 5 are provided with support plates 6, and a roller 7 is rotatably mounted at the lower end of each support plate 6.

[0025] The power motor 4, the speed reducer 3, and the winding roller 2 are mounted on the frame 1 to form a hoisting hoist, and the frame 1 is supported by four rollers 7, thereby facilitating the movement of the hoist.

[0026] As Figures 1-6 shown:

[0027] The horizontal shaft 5 is rotatably connected to the frame 1. A round seat 8 is provided in the middle of the horizontal shaft 5, a locking hole 9 is provided on the round seat 8, and locking mechanisms are provided at positions corresponding to the round seat 8 at both ends of the frame 1.

[0028] The locking mechanism includes a through-frame 10 slidably penetrating through the frame 1, and an insertion post 11 is provided at the end of the through-frame 10 close to the horizontal shaft 5.

[0029] By inserting the insertion post 11 into the locking hole 9 on the circular seat 8, the rotation limit of the horizontal shaft 5 is formed, thereby ensuring the position fixation of the roller 7 by the horizontal shaft 5 through the support plate 6. When the roller 7 rotates around the horizontal shaft 5 to the lower part of the frame 1, the hoist can move through the roller 7. When the roller 7 rotates around the horizontal shaft 5 to the upper part of the frame 1, the hoist contacts the ground through the frame 1, thus preventing the hoist from moving through the roller 7 during operation;

[0030] Among them, when converting the state of the roller 7, the insertion post 11 can be separated from the locking hole 9 by pulling the through-frame 10, thereby enabling the horizontal shaft 5 to rotate.

[0031] Furthermore:

[0032] The end of the insertion post 11 close to the horizontal shaft 5 is a round head. And a chamfer is provided at the end of the locking hole 9. Both can facilitate the insertion of the insertion post 11 into the locking hole 9 to form the locking of the roller 7 state.

[0033] Such as Figures 1-6 shown:

[0034] A spring 12 is provided between the through-frame 10 and the frame 1 to make the through-frame 10 press tightly against the circular seat 8.

[0035] Through the setting of the spring 12, it is avoided that the insertion post 11 automatically disengages from the locking hole 9, resulting in the automatic unlocking of the roller 7 state and affecting the use of the hoist.

[0036] Furthermore:

[0037] A baffle 13 is provided at the end of the through-frame 10 away from the horizontal shaft 5. And a pulling hole is provided on the baffle 13. It is convenient to pull the through-frame 10 by inserting the hand into the pulling hole to control the insertion post 11 to disengage from the locking hole 9.

[0038] Furthermore:

[0039] A rubber layer is provided on the outer surface of the roller 7.

[0040] Through the setting of the rubber layer, the noise generated during the movement of the hoist is reduced;

[0041] Furthermore:

[0042] Mounting holes are provided at the four corners of the frame 1.

[0043] Through the setting of the mounting holes, when in use, the frame 1 can be installed and fixed through the mounting holes, thereby further ensuring the stability of the hoist operation state.
