背景技术 Background technique

为节省资源,实施绿色施工,建筑施工现场临时道路和场地铺设常常采用一定规格的预制混凝土块,但这些具有额定重量的预制块运达现场后的卸车与铺设就位问题难以解决。若选用人工搬运,则劳动强度大,安全性差,费时费力,施工效率低,一般会选用起重设备来完成重物升降。考虑到升降机构为起重设备的重要机构,体积小巧、便于操作的微型起重机更是如此,而现有起重机工作过程中经常用到的起升机构装置,如CN101898731B公开了起重机的起升机构,包括电机、带制动轮的齿轮联轴器、制动器、减速器、卷筒齿轮联轴器、卷筒、钢丝绳、吊钩、轴承座,制动器与电机电气联锁,电机、带制动轮的齿轮联轴器、减速器、卷筒齿轮联轴器、卷筒依次连接,有补偿性能的齿轮联轴器便于整机安装,但该起升机构依靠电机控制吊钩实现重物的提升或下降,电能消耗较大,另外由于施工现场早期电力系统可能还没有配备,而且起重机工作流动性强,交流电使用不方便,若使用直流电成本比较高,因此,研发一种环境适应能力强、安全可靠、可采用无电工作模式的微型起重机起升机构尤为重要。 In order to save resources and implement green construction, prefabricated concrete blocks of certain specifications are often used for temporary roads and site paving on construction sites, but it is difficult to solve the problems of unloading and laying in place after these prefabricated blocks with rated weight arrive at the site. If manual handling is used, the labor intensity is high, the safety is poor, time-consuming and labor-intensive, and the construction efficiency is low. Generally, lifting equipment is used to complete the lifting of heavy objects. Considering that the lifting mechanism is an important mechanism of lifting equipment, especially the miniature crane that is small in size and easy to operate, and the lifting mechanism device that is often used in the working process of the existing crane, such as CN101898731B discloses the lifting mechanism of the crane. Including motor, gear coupling with brake wheel, brake, reducer, drum gear coupling, drum, wire rope, hook, bearing housing, electrical interlocking of brake and motor, motor, gear coupling with brake wheel The gear coupling, reducer, reel gear coupling, and reel are connected in sequence. The gear coupling with compensation performance is convenient for the installation of the whole machine, but the lifting mechanism relies on the motor to control the hook to lift or lower the heavy object. , the power consumption is relatively large. In addition, because the early power system on the construction site may not be equipped, and the crane has strong mobility, it is inconvenient to use AC power. If the DC power is used, the cost is relatively high. Therefore, it is necessary to develop a strong environmental adaptability, safety and reliability. The lifting mechanism of the miniature crane that can adopt the non-electric working mode is particularly important.

The lifting frame is connected with a counterweight 4 And the hoisting device, wherein the hoisting device includes a motor 8, a reducer 9 and a reel 10, a steel wire rope 12 is wound on the reel 10, and one end of the steel wire rope 12 is connected to a hook 13. There is a matching brake on the hoisting device to ensure the safe operation of the device. The ratchet bar 15 is connected to the column 7 of the crane base 11, the pawls 17, 21 are respectively connected with the drive levers 18, 20, the drive levers 18 and 20 are connected with the support plate 19 by a rotating pair, and the support plate 19 is fixed On the outside of the door frame 5; the upper ratchet 17 and the upper driving lever 18 are symmetrically arranged with the upper ratchet 21 and the lower driving lever 20 along the support plate 19; the driving levers 18, 20 are respectively provided with linkage pull plates 16, 22. The upper linkage pull plate 16 and the lower linkage pull plate 22 are connected with a soft core gate wire, and the other end of the soft core gate wire is connected to the joystick 1; the joystick 1 is installed on the rectangular frame 3 through the handle support 2, and the handle support 2, at least two chute structures are arranged so that the position of the joystick 1 can be adjusted to control the upper linkage pull plate 16 and the lower linkage pull plate 22 respectively.

将本实用新型的升降机构的吊钩13挂到重物14上,该机构在初始工作时需将升降架提升至高位进行蓄能,此时卷扬装置的制动器打开,控制操纵手柄1拉动上联动拉板16,上驱动拨杆18绕支撑板19转动,上棘爪17与棘条15脱离,可根据施工现场配电情况或采用电机8驱动或采用手动进行卷筒10收绳,下棘爪21从棘条15齿面上滑过,蓄能完毕后,制动器关闭,操纵手柄1复位,上联动拉板16、上驱动拨杆18与上棘爪17复位。 Hang the hook 13 of the lifting mechanism of the present invention on the heavy object 14. When the mechanism is initially working, the lifting frame needs to be lifted to a high position for energy storage. At this time, the brake of the hoisting device is opened, and the control handle 1 is pulled up. The linkage pull plate 16, the upper drive lever 18 rotates around the support plate 19, the upper ratchet 17 is separated from the ratchet strip 15, and can be driven by the motor 8 or manually to take up the rope on the reel 10 according to the power distribution situation on the construction site, and the lower ratchet Claw 21 slides over from ratchet bar 15 tooth surfaces, and after energy storage finishes, brake is closed, and operating handle 1 resets, and upper linkage pull plate 16, upper driving lever 18 and upper ratchet 17 reset.

重物14起吊时,由于配重4小于起吊重物14的重力,通过配重4与起吊重物14的微小重力差,在矩形框架3上施以操作人员自身重力使升降机构端总重力大于起吊重物14重力,控制操纵手柄1拉动下联动拉板22,下驱动拨杆20绕支撑板19转动,下棘爪21与棘条15脱离,重物14被提升,上棘爪17从棘条15齿面滑过,升降架运行至低位时,操纵手柄1复位,下棘爪21复位。由于上棘爪17与棘条15保持啮合,保证矩形框架3上操作人员重力消失后重物14不会下落。 When the heavy object 14 is hoisted, since the counterweight 4 is less than the gravity of the hoisted heavy object 14, through the slight gravity difference between the counterweight 4 and the hoisted heavy object 14, the operator's own gravity is imposed on the rectangular frame 3 so that the total gravity of the lifting mechanism end is greater than Lift the weight 14 gravity, control the control handle 1 to pull the lower linkage pull plate 22, the lower driving lever 20 rotates around the support plate 19, the lower pawl 21 is separated from the ratchet strip 15, the weight 14 is lifted, and the upper pawl 17 is lifted from the ratchet. Bar 15 tooth surfaces slide over, and when lifting frame moves to low position, operating handle 1 resets, and lower ratchet 21 resets. Since the upper ratchet 17 is kept engaged with the ratchet bar 15, it is ensured that the weight 14 will not fall after the weight of the operator on the rectangular frame 3 disappears.

重物14下降时,通过配重4与起吊重物14的微小重力差,控制操纵手柄1拉动上联动拉板16,上棘爪17与棘条15脱离,重物14下降,升降架再次升至高位,操纵手柄1复位,上棘爪17复位,由于下棘爪21与棘条15啮合,可保证升降架不会下落。若此时仍需将重物14下降至更低位置,则可打开卷扬装置中制动器进行卷筒10放绳,将重物14缓慢降至所需位置。 When the weight 14 is lowered, through the slight gravity difference between the counterweight 4 and the lifting weight 14, the control handle 1 pulls the upper linkage pull plate 16, the upper pawl 17 is separated from the ratchet bar 15, the weight 14 falls, and the lifting frame rises again. To the high position, the joystick 1 resets, and the upper ratchet 17 resets. Since the lower ratchet 21 is engaged with the ratchet bar 15, it can be guaranteed that the elevating frame will not fall. If still need to drop weight 14 to a lower position this moment, then can open the brake in the hoisting device and carry out reel 10 unwinding, weight 14 is slowly dropped to desired position.

最后说明的是,以上实施例提及的微型起重机升降机构,并不限定于本案所提供图示。本领域的普通技术人员应当理解,可以对本实用新型的技术方案进行修改或者等同替换,而不脱离本实用新型技术方案的宗旨和范围,其均应涵盖在本实用新型的权利要求范围当中。 Finally, it should be noted that the lifting mechanism of the miniature crane mentioned in the above embodiments is not limited to the illustration provided in this case. Those skilled in the art should understand that the technical solution of the utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solution of the utility model, which should be covered by the claims of the utility model.
