DETAILED DESCRIPTION

[0024] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0025] refer to Figures 1 to 5

[0026] A sideways hand-cranked structure for raising a lamp pole comprises a chassis 10 mounted on a base 12, a generator set installed in the chassis, and a lighting fixture provided with power by the generator set; a lamp pole seat 20 is mounted on one side of the chassis, the lower end of which is fixedly connected to the base; a lamp pole 30, initially in a horizontal position, is hingedly connected to the upper end of the lamp pole seat; the lamp pole is telescopically adjustable, and a lighting fixture 31 is mounted on the top of the lamp pole. A support frame 11 for supporting the lamp pole is mounted on the top of the chassis, away from the lamp pole seat; a reversing pulley 32 is mounted on the bottom end of the lamp pole, and a rope 40, which is a steel wire rope, is mounted on the lower portion of the lamp pole seat. The rope passes over the reversing pulley and passes through the chassis to connect to a manual winch 50 installed in the chassis, so that the lamp pole can be raised by winding the rope by the manual winch.

[0027] In this embodiment, in order to allow the lamp pole to stand upright on one side of the lamp pole seat after being lifted up, a hinge seat 21 is provided on one side of the top of the lamp pole seat, and the side of the lamp pole is hinged to the hinge seat.

[0028] In this embodiment, to prevent the lamp pole from tipping over and restoring after it is raised and to improve safety, a safety hook 33 is hingedly connected to the bottom end of the lamp pole, located above the reversing pulley. A fixing ring 22 that cooperates with the safety hook is fixed to the lower part of the lamp pole base, close to the lamp pole. Thus, after the lamp pole is raised into position, the safety hook is hooked onto the fixing ring.

[0029] In this embodiment, in order to ensure that the lamp pole can be stably connected to the lamp pole seat after it is lifted up, a limiting plate 34 is fixed to the lower part of the lamp pole and close to the side of the lamp pole seat, and a long hole 341 is provided on the limiting plate. A connecting seat 23 is installed on the side of the lamp pole seat close to the lamp pole, and a longitudinal slot is provided on the connecting seat. A limiting pin 24 for cooperating with the long hole is provided in the longitudinal slot, so that after the lamp pole is lifted into place, the limiting pin is inserted into the long hole, and then a pin is vertically passed through the limiting pin to pass through the end of the long hole to prevent the limiting pin from detaching from the long hole.

[0030] In this embodiment, in order to prevent the lamp pole from hitting the lamp pole seat due to inertia after being raised, an arc-shaped leaf spring 25 is hingedly connected to the upper part of the lamp pole seat near the lamp pole.

[0031] In this embodiment, in order to allow the rope to be better introduced into the manual winch, a fixing seat 26 is fixed at the lower part of the lamp pole seat and close to the side of the lamp pole, and a guide pulley 27 is installed on the fixing seat. One end of the rope is connected to the fixing seat via a pin 41, and the rope passes around the reversing pulley and the guide pulley through the horizontal hole at the lower end of the lamp pole seat into the chassis and is connected to the manual winch.

[0032] In this embodiment, the manual winch includes a wheel 52 rotatably connected to a mounting base 51 provided on the chassis. A large gear plate 53 is provided at one end of the wheel. A gear shaft 54 ​​is rotatably connected to the mounting base. One end of the gear shaft has a small gear 55 that meshes with the large gear plate. The other end of the gear shaft is connected to an extension shaft 56 extending from the front side wall of the chassis. The extension shaft is provided with a handle 57. A limit sleeve is also provided on the end of the gear shaft that extends from the mounting base.

[0033] In this embodiment, a ratchet 58 is fixed to the end of the gear shaft passing through the mounting seat, and a shaft 59 is rotatably connected to the mounting seat. A torsion spring 60 is sleeved on the shaft, one end of which is fixed to the mounting seat and the other end is fixed to the shaft, and a pawl 61 that cooperates with the ratchet is fixed to the end of the shaft passing through the mounting seat.

[0034] In this embodiment, the lamp pole can be telescopically adjusted by a winch mechanism.

[0035] Principle: By turning the handle on the outside of the chassis clockwise, the small gear shaft on the internal winch rotates in the same direction, and the large gear plate engaged with the small gear rotates in the opposite direction (counterclockwise). The number of wire rope windings on the large gear plate gradually increases, and the winch rotates along the winch. Figure 2 Recover the wire rope in the direction of the arrow. As the length of the external wire rope decreases, the angle of the lamp pole changes and gradually approaches the lamp pole seat. When the angle of the lamp pole becomes vertical, insert the limit pin into the long hole on the limit plate to complete the lamp pole lifting operation.

[0036] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0037] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.

[0038] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0039] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
